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

ABSTRACT NEW DISCOVORIES FOR THE REGENERATION OF DAMAGED NEURONS (Possible cures and relief for millions of people) Normally‚ neurons in the central nervous system (the brain and spinal cord) cannot regenerate injured nerve fibers‚ limiting people’s ability to recover from brain or spinal cord injuries. Repair of the central nervous system and restoration of voluntary motor activity through axonal re-growth has long been considered impossible in mammals. Over the last decade‚ numerous attempts

system consists of the brain‚ spinal cord‚ and nerves. 2. The afferent nervous system consists of all outgoing motor pathways. 4. Ependymal cells engulf and destroy microbes and cellular debris in inflamed or degenerating brain tissue. 5. Oligodendrocytes form myelin sheaths around nerve fibers in the CNS. 6. Nerve fibers with many Schwann cells forming a thick myelin sheath are called myelinated fibers‚ or gray fibers. 8. Most of the neurons in the brain and spinal cord are unipolar. 9.

birth defects. It is present in about 1 in every 1000 births. This birth defect is part of a group called neural tube defects. The neural tube is a hollow structure where the brain and spinal cord form. This happens at the end of the first month of pregnancy when the spinal cord is developing. As a result‚ the spinal cord and nerves become damaged. This defect causes an opening in the back that can be visible or hidden under the skin. There are 3 main types of Spina Bifida. One is spina bifida occulta

Spina Bifida Spina Bifida is a rare birth defect that causes a malfunction in a baby’s spine when it develops. The spinal column is supposed to be closed all the way around‚ but for some children it never fully closes. This allows spinal nerves‚ cords‚ and sacs of fluid that would otherwise be enclosed be exposed. It can lead to serious damage like paralyzation. 8 children are born with this in the United States every day. “SB mostly occurs during first trimester of pregnancy.” Although nobody is

NEUROLOGY INTRODUCTION: Nervous System- the body’s communication network - coordinates and organizes 3 Division: 1. CNS- central nervous system - made up of the brain and the spinal cord 2. PNS- peripheral nervous system - includes nerves that connect the CNS to the remote body parts - relays and receives messages 3. ANS- autonomic nervous system - regulates the involuntary function

American Academy of Orthopaedic Surgeons. For people suffering from lumbar spinal stenosis‚ in which nerves are pinched in the lower back‚ lying in any position can create significant pain except‚ perhaps‚ when the knees are bent. "When these people are sleeping‚ whether on the back or side‚ they like to bend their knees because that brings their legs up and opens up the back of their spine‚" said Dr. Shamie. Spinal stenosis patients often place a pillow under their knees when sleeping on their back
