How To Calculate Your Ideal Body Weight

You can start losing weight now by setting yourself up for success. By that I mean – be realistic about what a healthy ideal weight is for your age, height and body frame. By setting an ideal weight is realistic, but one that stretches you, the likelihood of you reaching your goal weight is much, much greater.

Do you even know what your ideal weight is? If not, this is exciting – you can start today by becoming an active participant in your own success weight loss story. To do this:
Go online and educate yourself.
Use your favorite search engine.
Type in “ideal body weight”.
For a second search, also type in “BMI” (Body Mass Index)
Research some sites and use three that you like.
Calculate what your ideal body weight is with all three sites.
Using three results is very useful as you will note a standard and it will be more believable for you.
Decide on an ideal weight for yourself within the range calculated.

Congratulations, you are one of few who really do know what their ideal weight is. You are no longer just making an uneducated or uninformed guess. It is important for us, especially for women I feel, to keep a realistic and healthy perspective on the issue surrounding weight and identify what is healthiest for each of us. There are many women whose weight is at a healthy place which is when the BMI between 20 and 24, but they are still trying to lose weight to fit into the image of what a healthy body weight is in the eyes of the media and society. So before you start any weight loss program, educate yourself as much as you can, speak to your doctor, nutritionist or an expert at the gym. Take charge of your body and your life. There is no need to leave it in the hands of those who go by hearsay. Calculate your own BMI. This will give you a good idea of how much weight, if any, you really need to lose. To calculate your BMI, I have found this site very easy to use and to understand: http://www.halls.md/body-mass-index/bmi.htm

With information that you can trust, some great tools, willingness and commitment you can lose weight and live in a body that you can be proud of.

Body Building Tips For Safety

Staying fit and healthy takes a certain amount of determination even if your bodys natural metabolism is fast enough that you can eat whatever you want and not gain any weight. However, for some of us, simply staying fit and trim is not what we strive for in life. Instead, we want to have the ultimate in physical perfection. We want to look like the Statue of David, standing there with a perfectly fit body and muscles that look as if they could snap tree trunks like twigs. For some of us, Arnold Schwarzenegger is our hero and our icon, we look up to him not for his fantastic action movies but instead for his amazing success on the body building competition circuit. Unfortunately, simply looking up to celebrity body builders and wanting a body that looks like it was carved from marble by some of the great renaissance artists is not enough to ensure that your body will look as if it is in the ultimate physical condition. No, instead we have to dedicate countless hours to working out if we want our bodies to look as strong and defined as possible.

Hard work and dedication are the two words that come to mind when someone thinks about improving your bodys appearance. Working out to improve your physique is not simply a hobby that one can have and do on the weekends. No, it must be done each and every day of each and every week until you are completely happy with the way that your body looks. Also, body building takes far more effort than simply spending a few hours at the gym each morning you have to eat right and take the appropriate supplements if you want to have the body of a Greek God. Unfortunately, having such an impressive physique can also come at a price if you are not careful about what you do.

While eating healthy foods and spending a few hours a day at the gym while working out has never hurt anyone (other than a few aches and pains), there are many aspects of the sporting world that can. One such problem with body building is the amounts of supplements that people choose to take in order to help their body building progress along. Although some supplements like protein and various vitamins are good for you, other body building supplements can be extremely toxic to your liver and kidneys in the long term. Also, if you want to get into body building, you must be sure to stay away from steroids, as they can have detrimental side effects that could leave you in a world of hurt when your body building career is over. Taking a more natural approach to body building seems to be the best solution for your long term success.

Build The Prefect Body Muscles

Have you been to the sports center recently? If you have, you must have noticed all those bulging muscles and toned bodies. Ever wonder how more and more people seem to be getting that way without too much effort on their part? Dont get me wrong. Building up a body is hard, agonising, rhythmic work. But everyone can benefit by using the right body building vitamin supplements.

Every time the expression body building vitamin supplement comes out, most people begin to think of steroids or hormonal drugs. While it is true that some of the body building supplements available in the market fall in this category, there are other body building supplement available which are more holistic in description. These are the body building supplements I am referring to. Plainly put, think of them as a balanced and dietary food supplement that cater to the overall needs of anyone who indulge in a certain amount of body building activity.

As I mentioned earlier building up a body is sore work. Most people who hit the gym burn up calories at an astonishing rate. In order to retain the body balance and beef up in the literal sense of the term, they need to have body building supplement. In such cases, the body building supplement act as power sources that enable the body builders to exercise more rigorously and build more muscle. Due to their higher than normal metabolic rate, they need to have a diet that is not just protein rich, but also has a permutation of all other essential nutrients in the right mix.

There are a number of companies making products like body building supplements. However, a word of caution is necessary before you can run pout and buy yourself some body building supplement. In fact, before you go for any kind of vitamin supplements, it would do you good to get the opinion of your medical doctor. If you are enrolled with any decent sports center, chances are you have access to a trained nutritionist. Make use of this! Get to spend some time with them discuss your body building objectives, your exercise routine, your diet, your general treatment among other things so that they can suggest the right kind of body building supplement for you.

Once you have done all this, maintain with your regular aerobics studio and see the outcome for yourself! You will notice that not only do you add size far more with no trouble, but that your body manages the weight to give you the great body you have always dreamt of.

The Importance Of Body Wash

As tradition goes we have been using soap since the time we are born. Before soap, there must have been some other and more natural product considering the time factor. It has been a very important part in cleaning our body. Even though soaps used are more chemical based which can cause harm to anyone's body. New products have always come in the market and keep getting better every time and are more considerate towards your body.

Now things have changed, even soaps have a stiff competition from the body wash. It is said that the body wash are better in cleaning your body due to the liquid which has the properties of the necessary nutrients for gentle exfoliation. This becomes very important as our body goes through wear and tear and it needs to relax which can happen by the use of different types of body wash.

The different type of body washes help in rejuvenating your skin and hydrating your dehydrated body. Different type of herbal products which are used are yogurt, cucumber, aloe Vera, vitamins B, strawberry, lavender, coco, oatmeal, rosemary, lavender and many more to add that touch of perfection to your body. It has a lasting smell which keeps you as well as others fresh with a lingering aroma.

These herbal products just make your bath more than a daily chore. It becomes an experience which you comes across everyday while having a bath. A fresh morning and a refreshing evening which can be very beautiful and very exciting start of the day. The use of herbal products makes a lot of difference. But you should keep in mind that this stuff should be genuine enough to be used on your body. So buy products which are from a good brand and are easily available.

Back Pain's Newly Discovered Cause

This article is about a cause of back pain which most people, including doctors, don't understand.

This back pain cause is not disease such as cancer or arthritis. It is not injury such as falling off a ladder. Also, it is not a mentally caused pain...it is a very real pain.

This back pain is caused by incorrect use of voluntary muscles. Voluntary muscles are muscles you can control. Do this. Lift your arm. There you used voluntary muscles.

You can cause pain by using, or not using, your voluntary muscles incorrectly. By using one hand to bend the fingers of your other hand backward you can cause pain. This is an example of incorrectly using voluntary muscles and causing pain.

This discovery, called Denlinger's Discovery(TM), is about another cause of pain throughout the human body and how to fix it. Denlinger's Discovery came about by applying engineering basics to the human body. Using these engineering basics one can also increase the load carrying capability of the body. In this article we'll only look at one function, of several functions, of the back.

In 1759 a Switzerland born scientist named Leonardo Euler (1707-1783) developed the first, most basic formulas about the relationship of the height to the thickness of a column. A summary of this formula is that the thinner a column or post, as compared to its height, the more likely it will fail (ie, break) by bending rather than by crushing. Also, if the column has supports in the middle to keep it from bending, it will be able to carry a much heavier load.

Here's an experiment you can do. get a long, skinny twig from a tree or bush. Stand it up on a table vertically and push down on the top with a finger. Feel how easily it bends. If you push too hard it will break. Next, place your other hand on the side to keep it from bending so much and press down on the top again. Feel how much stronger the twig is now.

You can see an example of this principle applied in daily life by looking at a very tall television transmission tower. Typically these towers have wires, called guy wires, going from the middle (often from quarter, half and three quarter points or more) down to the ground. These guy wires keep the tower from bending in the middle, so it can carry a load to a much greater height.

The spine in the lower back of the human body has voluntary muscles which can act like guy wires to keep the spine from bending from side to side. Looking in the Doctor's Bible, "Gray's Anatomy", you can see these muscles in one of the drawings looking at the rear of the body. These muscles are called "quadratus lumborum" (they are shown in a posterior view of the back and described in the section on Deep Muscles of the Abdomen). Correctly using these voluntary guy-wire-type muscles per Euler's formulas could fix a problem called scoliosis. Currently doctors use braces and even surgery to correct scoliosis. As long as the muscles and nerves are in place and not damaged and the person is willing and able to learn how to use them and s/he then trains his or her guy-wire-type muscles the scoliosis problem could be fixed by correct use of voluntary muscles.

The same basic principle of preventing too much bending, using other muscles, can be applied in another direction to strengthen the spine by preventing too much curve forward and backward. There are other engineering basics which can be applied to the back and other parts of the human body which will be covered in other articles.

How to Effectively Learn Human Anatomy

When a person first takes on the challenge of learning the anatomical structures and functions of the human body the task can seem daunting. There are specific ways an individual can increase their efficiency by utilizing proper educational resources and methods to effectively learn anatomy. A dedicated persistence is necessary to learn human anatomy effectively.

The typical method of learning human anatomy is by taking a systemic approach, in other words, studying each system of the human body one at a time. After the different systems have been learned a person typically learns how the different systems function and support each other. A systemic approach is one of the most effective methods of learning human anatomy.

There are many methods on how to actually go about studying each system and their functions. Each person learns differently, but most people begin their anatomical studies with the skeletal system. The skeletal system is the most simple of all of the human anatomy systems. Once the skeletal system is mastered it is suggested that an individual learns things such as anatomical plains and positions. This provides a solid foundation to remembering the names of the vast array of muscles, attachments, ligaments, etc. After these terminologies have been learned most people begin tackling the more complex systems of the human body because they are prepared with the proper terms and vocabulary.

Throughout the education process there are numerous resources that can be utilized to learn anatomical structure and functions. Some people prefer to learn directly from a textbook and some people learn more effectively using software or visual teaching aids, such as anatomical models and posters. There are also many free online resources that an individual can use to learn basic human anatomy.

Throughout the comprehensive learning process of the human body it is important to stay persistent and utilize a wide variety of resources. If one way of absorbing knowledge is not working the best for you it is wise to try a different method. You may find that a simple change of media increases your efficiency greatly. Remember to start simple and learn the general terminology first and it will greatly increase your success with learning the comprehensive systems of the human anatomy.

A fantastic way to learn human anatomy is to utilize free human anatomy online resources such as vAnatomy.com. For visual, hands on, learners and teachers many people find anatomical models/charts to work effectively in the educational process.

Brendon Mitchell owns and operates online anatomy resources vAnatomy.com and VisuMedical.com. These sites are dedicated to providing high quality medical and anatomy educational resources.

Wolf Anatomy

The Gray Wolf, being the largest of the canid family, stands about 26 to 28 inches high at the shoulder for an adult male; a body length of 40 to 58 inches and tail approximately 13 to 20 inches long. The female wolf is roughly 15 to 20 percent smaller. The weight of North American wolves varies between 40 and 175 pounds, with average weights being between 60 to 100 pounds. Despite legends of 200-pound wolves, the heaviest wild wolf only weighed 175 pounds.

The gray wolf has a broad face and appears larger than it really is because of the ruff of fur below the ears. The eyes are usually a golden-yellow and at night shine a greenish orange. Its ears are approximately 2 inches long and the nose as much as 1.5 inches wide.

The wolf's body is built for traveling and its chest is narrow, allowing it to push more easily through the deep winter snows. The coat is thick and fluffy with long guard hairs that repel moisture and a thick wooly undercoat for insulation. The guard hairs may grow to 4 or 5 inches in length. The winter coats are then shed in the spring. The legs are long with oversized feet which act like snowshoes to enable the wolf to travel more easily in the snow.

The color of wolves range from all shades of gray, tan and brown to pure white or solid black, with the Red wolves having reddish coats. The tip of the tail is often black. Many of Canada's high Arctic wolves are creamy in color. White hair shafts have more air pockets than coloration pigment and therefore provide better insulation.

The wolf has extremely strong jaws with a crushing pressure that is twice that of a German Shepherd. The upper jaw has six incisors, two canine teeth, eight premolars and four molars. The lower jaw has six incisors, two canines, eight premolars and six molars. The incisors at the front of the jaw are used to cut flesh from prey. The canines, wich may reach two inches in length, pierce into flesh to hold prey. Premolars and molars are used for slicing and grinding.

The surface sense of smell in a wolf is 14 times that of a human and the degree of sensitivity to smell is 100 times more than the sensitivity of man. They can pick up a scent at least a mile away or more. According to Canadian naturalists, a dog's hearing is about sixteen times that of man. A wolf's hearing is even more acute than that. A wolf can hear as far as six miles away in the forest and ten miles away on the open tundra. Wolves have been known to respond to human imitations of wolf howls from three miles away.

The wolf's sense of sight is relatively poor compared to their smell and hearing. Observations have shown that their sight is at least as acute as that of humans. Naturalists believe that wolves are quite nearsighted and that they can clearly see details up to about 75 feet. However, the wolf's peripheral vision and ability to detect motion is excellent. The outer perimeter of a wolf's retina is extremely sensitive to movement. Their night vision is far superior to that of man's.

Naturalists have found that wolves tend to distinguish the colors red and yellow from other colors. The thinking is that perhaps because of red being the color of blood and yellow being that of urine. In any case, they seem to believe that wolves become more interested in colors that have a reddish base and have a strong ability to detect red from other colors.

Because of disease, parasites, injuries and hard winters of food shortages, wolves in the wild are likely to live less than 5 years. The true enemy of the wolf is man himself. Legal and illegal hunting, collisions with vehicles, trapping or predator control has wiped out a good many of the wolf population. In contrast to that, wolves in captivity can live as long as 18 years. Wolf Haven, near Tenino, Washington, had one wolf that lived to be over the age of 18 and currently has a wolf 17 years of age.

The author has long admired the wolf as being a fascinating and beautiful creature and has devoted a website to share with other wolf lovers. It contains wolf facts, pictures, interaction with man, wolf news clips, wolf artifacts and other interesting information. Please visit the site at http://www.wolvesinformation.com.

Anatomy For Fitness Professionals

Instead of just explaining, here's a few examples of anatomy mnemonics at work:

- FEMoral hernias are more common in FEMales. The key to this easy mnemonic is remembering the correlation between the word Femoral and Females.
- To remember the adrenal cortex layers and products, repeat to yourself "Go Find Rex, Make Good Sex". Pretty easy to remember, isn't it? The answers lie in the first letter of every word.

- Layers: Glomerulosa, Fasiculata, Reticulata Respective.

- Products: Mineralcorticoids, Glucocorticoids, Sex hormones.

Because the latter example uses humor and a racy theme, your mind easily takes notice and encodes it to memory. That's why anatomy mnemonics are the easiest, fastest and best way to learn anatomy -they are easy to personally identify with.

When you've been examining diagrams, books and notes all day, it's difficult to go home and focus on more visual study. For this and many other reasons, most scholars now prefer to learn mnemonics through audio. You can learn mnemonics anywhere through this method, and give your eyes a rest while doing so. Many listen to mnemonics on their iPods before bed, or while traveling in their car.

The best anatomy mnemonics can be discovered in one easy place. On top of that you can access them in one convenient audio system.

The Best Anatomy Mnemonics

Mnemonics are recognized by many as the best way to learn and memorize almost any subject. They're used by bartenders to remember drink recipes, taught in elementary schools (remember the alphabet charts with A for Apple? That's a mnemonic!), and are favored amongst academics and professionals for teaching a wide array of subjects. Possibly one of the most celebrated uses of mnemonics is to teach human anatomy and physiology.

Contrary to what is commonly thought, text books and lectures are not the most effective way to learn and memorize anatomy. How many late nights have you spent trying to memorize information you've read? It all seems blurry by the next morning. That's because text books do not prompt an emotional response. In order to encode or create a memory, your mind relies on certain types of information that it can easily grasp. Mnemonics are designed to apply proven memorization cues to important information, such as human anatomy.

Instead of just explaining, here's a few examples of anatomy mnemonics at work:

- FEMoral hernias are more common in FEMales. The key to this easy mnemonic is remembering the correlation between the word Femoral and Females.
- To remember the adrenal cortex layers and products, repeat to yourself "Go Find Rex, Make Good Sex". Pretty easy to remember, isn't it? The answers lie in the first letter of every word.

Coral's Anatomy

You may have encountered the term cnidarians once in biology perhaps but you forgot the meaning of the word. Let me refresh your mind a bit with the meaning of this term. Cnidarians are small group of animals found in the sea and the most common example of this family-corals. Yes, the uniquely-shaped and diversely colored corals belong to this family. You may have seen corals more than once in your lifetime and wondered how corals are made. We are going to know more about the anatomy of coral polyps and how they are made into what we see now.

A coral is produced by the accumulation of tiny organisms that are called polyps. They are tiny elongated organisms that resemble the form of a tube. What is unique about this organism is that it is symmetrical, meaning one side is just like the other and when cut transversely, both becomes equally identical. They have tentacles that they use to procure food. The maximum number of tentacles that the polyps have is eight. There are different types of cells that make up the coral. Nematocysts for example, are found in the tentacles. They have toxins that they secrete to stun the small organisms, mostly crustaceans, and later on devour as food. They act as a defense and at the same time as a weapon to capture its prey. Another would be the glandular cells found in the middle cavity of the polyps. It releases enzymes that help polyps break the food they engulf after stunning it with toxins. Epithelio-muscular cells have a different function since they help polyps to voluntarily contract allowing movement. The mucus-producing cells release viscous liquid that helps remove foreign particles out of the polyp's body. It basically cleans the internal and external parts of the polyp. When it comes to the reproduction of polyps, the interstitial cell is responsible for the differentiation between the male and female cells.

Some polyps are nocturnal when it comes to feeding, meaning they actively feed on night more than during the day. They protect themselves by keeping their tentacles during the day and would protract their tentacles offensively during night time in order to capture its prey. Corals are produced by the hardening of calcium carbonate that is released from the skeleton of polyps after they die and can be classified as soft and hard corals, depending on whether protein is predominant in the remains or not. Corals are indeed unique and deserve to be protected since it is home to hundreds of other life forms found in the sea and ocean floor.

To better appreciate the under water, one must bring along a fog spray that keeps glasses and goggles clear all the time. Goggles with no fog only means one thing, clear vision on everything you wish to see down under.

Anatomy of the Paranasal Sinuses

The hollow air spaces in the body are known as sinuses. There are about 60 sinuses spread throughout your body. When you think of "sinusitis" or "sinus infection", you are talking about the paranasal sinuses. Each of the paranasal sinuses has an opening (ostium) into the nasal cavity. To function normally and stay healthy, each sinus cavity must be able to drain mucus and exchange air through these openings.

The paranasal sinuses are composed of:

    * Ethmoid sinuses
    * Frontal sinuses
    * Maxillary sinuses
    * Sphenoid sinuses

The Ethmoid Sinuses are located behind the bridge of the nose in the ethmoid bone. These sinuses consist of 6-12 thin-walled cavities. These are divided into anterior, middle and posterior groups. The posterior group drains into the nasal cavity towards the rear. Sometimes one or more of the posterior group opens into the sphenoid sinus. The middle group and anterior group drain into the middle of the nasal cavity.

The Frontal Sinuses are located behind your eyebrows in the frontal bone. They can differ in size from left to right and in about 5% of people they are not present at all. The frontal sinuses are absent at birth, but are well-developed by age 8, and reach their full size around puberty. The frontal sinuses drain into the middle part of the nasal cavity.

The Maxillary Sinuses are the largest of the paranasal sinuses. They are located behind each cheekbone and are roughly triangular in shape. The maxillary sinuses drain into the middle par t of the nasal cavity. The opening into the nasal cavity is found high up on the sinus wall and these sinuses do not drain well with the head upright.

The Sphenoid Sinuses consist of one or two sinuses located deep behind the bridge of the nose in the sphenoid bone. These sinuses drain into the back part of the nasal cavity. The openings of the sphenoid sinuses are also located high on sinus wall and do not drain well when the head is upright.

The sinus lining is composed of epithelium cells (with and without cilia), goblet cells, and basal cells. There are also wandering immune cells present (lymphocytes and mast cells). The sinus lining forms a physical barrier that keeps bacteria, pollutants and allergens from entering our bloodstream and tissues.

The sinus lining also produces mucus from the goblet cells. This mucus traps the pollutants, bacteria and allergens. The mucus also has special antibodies and enzymes that;

    * prevent viruses and bacteria from sticking to the sinus lining
    * help our white blood cells to recognize viruses and bacteria as invaders and to kill them

The ciliated epithelial cells work together to sweep out the mucus that has foreign materials and microorganisms. This process is known as mucociliary clearance. These ciliated cells are very sensitive to humidity, pollutants and toxins. If they don't function well, we can expect sinus infections to occur.

The purpose of the sinuses is unknown, but here are some of the possible functions:

    * Makes the front of the skull lighter
    * Makes the voice more resonant
    * Provide a crumple zone for facial blows
    * Protects the eyes and teeth from rapid temperature changes
    * Heating and moistening incoming air

The Human Anatomy

You can see everything from a bird's eye view. The same can be said for a doctor who not only studied the human anatomy, but included studies in areas like clinical pathology, microbiology, pharmacology, drug dosage, epidemiology, and therapy to get a bird's eye view of the human body and how to treat it. This is the doctor who truly cares; this is the doctor who saves lives.

The human anatomy is very complex, and studying the human anatomy through course after course can get confusing. When material is broken up from course to course, you can forget a lot. Try studying the human anatomy as a whole at one time. This way, you get the bigger picture and can relate one concept to another.

Whether you're just starting out in your medical career or are a long-time health practitioner, it's essential to get a good overview of the human anatomy to avoid any costly mistakes. Medical malpractice lawsuits are on the rise. You may know someone who has gone through this. The doctor spends hours and hours sitting through a deposition, has to respond to numerous discovery requests, and has fear of his/her license being taken away. And, for what? Because he/she dismissed a patient without doing an MRI or some other method that deviated from the standard of care. There is no room for mistakes in this field for dismissing patients because they appear "okay". Don't let that be you.

A good course on the human anatomy will have lectures, reading materials, and illustrations carefully diagrammed and labeled. Lectures help the auditory learner. Reading materials help the visual learner. Visual stimuli is important for retaining information. This is why illustrations are so vital. Combining these three methods of learning, you are sure to retain what you have reviewed.

There are many things to learn about the human anatomy, so find one that focuses primarily on basic physiology first. Study the different tissues and cells and about envelopes of the body. Learn about all of the different organ systems, how they relate to one another, and how they communicate with one another. Other useful studies that will help you understand the human body in depth is: clinical pathology, microbiology, pharmacology, drug dosage, epidemiology, and therapy.

Clinical pathology teaches how to diagnose diseases by analyzing bodily fluids placed on slides in a laboratory. Microbiology is useful to medicine because it offers explanations of how the human body becomes diseased by viruses, bacteria, parasites and fungi. Pharmacology studies the effects of drugs introduced to the body. Drug dosage concerns the appropriate quantities of a drug given to a patient to treat or alleviate discomfort. Epidemiology studies health in society. Therapy is useful in recovery. It is through all of these measures that a doctor gets an appropriate view of a patient's illness. The doctor can look at a patient's ailment from all sides armed with this knowledge and can come to an accurate diagnosis. The type of person who takes a course such as this will be the doctor who truly cares about his/her patient.

Make a difference in a patient's life. Make a difference in your own. Without studying the human anatomy as it relates to society, one cannot understand the environmental factors on health. Without studying microbiology, one cannot understand where or how a disease is introduced to a body. Without therapy, one cannot understand what allows for rehabilitation. Without all of these different angles covering the complete health of the human body, one cannot save lives. Studying a course focused on all of these angles is essential.

Anatomy of a Neuron Cell

The nervous system is essential to the body in several ways. It allows us to detect changes in the surroundings but additionally the ability to react to it. The nervous system is categorised into two main sections:

1. The central nervous system - The spinal chord and the brain

2. The peripheral nervous system - All the other neurons that connect to the central nervous system

Specialist cells called receptors are used by the body to sense stimuli (changes in the environment) and send information down nerves. Receptors are most commonly located at specific sensory organs, such as:

Eye: Receptors here are able to detect changes in light

Skin: Receptors here are sense changes in pressure and temperature

Tongue: Receptors here are sensitive to chemicals in food

Ears: Receptors here are sensitive to sound and changes in position (so we can keep our balance)

Nose: Receptors here are responsible for changes in chemicals in the air

When a receptor detects some form of stimulus it sends the information as an electrical signal down nerves (neurons). The brain is then able to gather information about changes in the environment and co-ordinate a response. This response is more rapid and often involves effectors.

Effectors

Effectors are glands or muscles that the brain sends commands to via nerves. Any mobile body part of the body is an effector as are internal glands: a muscle used to lift your leg up is an effector; a muscle that controls the eye lid is an effector; a gland that releases a hormone into the cardiovascular system is an effector.

Reflex

Generally when a receptor detects stimuli causing an electrical message to travel down the sensory nerve to the central nervous system. Here the brain organises a reaction (thinking time) and another electrical impulse is sent down down the motor neuron.This in turn sends an electrical signal to an effector and the effector produces a response:

Stimuli->Receptor->Sensory neuron->CNS->Motor neuron->Effector->Response

In some cases this response time is not fast enough and could cause us to get injured. At these times the nervous system skips out the CNS to speed up the action: a receptor detects a stimulus and an electrical impulse travels down the sensory neuron. Here it sends an electrical signal down a relay neuron which skips out the brain and communicates directly with a motor neuron which causes an effector to produce an action:

Stimuli->Receptor->Sensory neuron->Relay neuron->Motor neuron-Effector->Response

Though a relay neuron is part of the CNS, this is more rapidly as it skips out the thinking time.

Nerve Structure

Neurons are a type of cell that is capable of transmitting electrical impulses. Neurons are involved in the whole system. Without them we would not be able to think or move! There are 3 main types of neuron:

1.Sensory neurons
2.Relay neurons
3.Motor neurons

Despite these different neurons having different places within the nervous system, they have some central anatomical features:

Axon: This is what an electrical message travels down

Myelin Sheathe: This insulates the Axon and speeds up the electrical impulse.

Dendrites: These overlap with other neuron dendrites at junctions called synapses. This is where nerves communicate with each other.

Nerve Synapses

Synapses are the point where nerve cells (neurons) pass impulses between each other. The impulse travels down the axon. At the Dendrites (dendrons) it comes to a synapse. The impulse causes a neurotransmitter to be released across the neuron synapse. The neurotransmitter causes the next nerve cell to pass a command down its axon. In this way a nervous impulse can travel all over the body, controlling all sorts of processes and responses.

Study Anatomy

Study Anatomy

There are many different reasons for wanting to study anatomy. Maybe you want to learn human anatomy as a part of an educational program. Or, maybe you need to learn how the human body functions in order to further your career. Amazingly, you might just want to learn about the human body for personal reasons. Whether your reason is academic, business or personal in nature, learning about the human body is very intense, but rewarding.

Definitions
