Nerve Study

This picture shows you how a regular nerve, one of a person with out Multiple Sclerosis, looks when compaired to the nerve of someone diagnosed with MS. The myelin sheath is a white, waxy coating  that covers the nerve cells and allows conduction of nerve impulses between cells, working in much the same way as the insulating coating on a wire does. The bodys immune system eats away at the myelin in someone with MS. MS is believed to initiate an attack on the myelin, resulting in lesions—bare spots and scarred areas along the nerve. Conduction of the nerve impulse is then slowed or halted, producing the neurologic signs and symptoms of MS. Destruction of myelin, a process known as demyelination, can also lead to “cross-talk” between nerves—abnormal nerve-to-nerve signaling, which also may produce symptoms.
