If damage to a nerve is severe or close to the cell body the entire neuron may die as well as other neurons that are normally stimulated by that particular nerve‚ may die as well. However if the cell body remains intact‚ cut or compressed the axons of the peripheral nerves can regenerate. However post trauma axon regrowth never exactly matches what existed before the injury‚ and a lot of the

blanks 61 True/False 62 Bibliography 64 Summary The 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 central nervous system consists of the brain and spinal cord and serves as the collection point of nerve impulses. The peripheral nervous system includes all nerves not in the brain or spinal cord and connects all parts of the body to the central nervous system

From the repeated injuries Sannu is having repeated nerve damage. When someone has Leprosy and it is untreated they can lose sensation in that extremity due to the body’s defense mechanism. This will cause loss of feeling in the skin and weakens muscle. B. Leprosy can affect the skin and Schwann cells of peripheral nerves. Which events of sensation processing are most likely not functioning properly in Sannu’s leprosy? Generation of nerve impulses is probably not working properly. Sensory neurons

The nerve that controls sensation and movement in the thumb and first three fingers‚ runs through this passageway along with tendons to the fingers and thumb. Carpal tunnel syndrome (CTS) is a median entrapment neuropathy that causes paresthesia‚ pain‚ numbness‚ and other symptoms in the distribution of the median nerve due to its compression at the wrist in the carpal tunnel. The median nerve and several tendons run from your forearm to your hand

piriformis muscle and the pelvis fascia and nerves coming from this plexus converge toward the lower part of the greater sciatic foramen and unite to form a flattened band‚ which continues primarily as the sciatic nerve. All nerves that root from the plexus either have anterior or posterior divisions and the posterior division has less nerves than the anterior. The posterior division contains the superior gluteal nerve (L4-S1)‚ inferior gluteal nerve (L5-S2) and the nerve to piriformis (S1‚ S2). The anterior

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 body in order. It helps to control all of the body systems and organs‚ keeping them working like they should. The brain also allows us to think‚ feel‚ remember and imagine. In general‚ the brain is what makes us behave as human beings. The brain communicates with the rest of the body through the spinal cord and the nerves. They tell the brain what is
