The nervous system is a very complex system in the body. It has many‚ many parts. The nervous system is divided into two main systems‚ the central nervous system (CNS) and the peripheral nervous system. The spinal cord and the brain make up the CNS. Its main job is to get the information from the body and send out instructions. The peripheral nervous system is made up of all of the nerves and the wiring. This system sends the messages from the brain to the rest of the body. The brain keeps the

The first thing that happens when we see something is light is focused onto the retina by the eye. The photoreceptor cells absorb that light. This layer of cells takes the light and converts in into electrochemical signals. There are two types of these cells‚ rods and cones. Rods are located in the retina‚ mainly the peripheral regions. Rods are rod-shaped cells and are used for night vision because they respond better to dim light than bright light. This is why people may find that if they look

function of the Autonomic Nervous System Introduction: The organs of our body are controlled by many systems in order to function correctly and efficiently in order to survive within the environment we live in. These include the heart‚ stomach and intestines and other vital organs and body systems. All of the systems in our body are regulated by a part of the nervous system called the autonomic nervous system (ANS). The ANS is part of the peripheral nervous system and it controls many organs

When you are diagnosed with a brain tumor‚ it is a scary life-changing event. The brain is one of the most important vital organs‚ and if found with a brain tumor‚ go to the doctor for immediate help. The brain and spine make up the central nervous system or CNS. Where each vital function is controlled. So if you have a tumor in your CNS‚ it can effect everything you do like: your thought process‚ how you talk‚ and even how you can walk. There are two types of brain tumors‚ primary and secondary

Include in your outline the major distinctions among these systems. Human Nervous System – Overview The human nervous system is composed of all nerve tissues in the body. The functions of nerve tissue are to receive stimuli‚ transmit stimuli to nervous centers‚ and to initiate response The nervous system has two distinct parts -- CENTRAL and PERIPHERAL
