NUR 290 Lecture Notes - Lecture 27: Multiple Sclerosis, Oligoclonal Band, Myelin
Document Summary
It"s an autoimmune disease that affects the myelin sheath of the central nervous system (cns). This leads to inflammation and scarring of the nerve, which causes a decrease in nerve transmission. This is why many patients experience sensory and motor problems. It"s an autoimmune condition, which means the immune system is actually attacking the myelin sheath found on the nerve. If these are present it shows there is inflammation in the cns: evoked potential studies (sends electrical signals to the cns and sees the response). You have to understand the anatomy and physiology of the nerve cell (neuron) in the central nervous system. Dendrites: receive the signal needed to create some type of action. Soma: (which means body) and this structure helps pass on the signal it just received from the dendrites to the rest of the neuron. Then the signal goes down and passes where the soma of the neuron and axon connect at the axon hillock.
