Question 1

does m.s. only attack the central nervous system?

Accepted Answer

Yes: Multiple sclerosis (ms) is an autoimmune disease (body's defense system attacking itself) that involves the central nervous system. Central nervous is composed of the brain and spinal cord. Myelin sheaths protect and insulate nerve cells; in ms the myelin sheaths on the axons (longer parts of the nerve cells) are inflamed and damaged,  leading to scar development seen in white matter of the brain.

Question 2

what makes up the central nervous system?

Accepted Answer

CNS=Brain+SpinalCord: Limits of brain tissue are the meninges, a fibrous cover. The spinal cord usually ends at the first lumbar vertebra, just below the last rib. Below that are nerves to your legs called the cauda equina, named because they look like a horses' tail.

Question 3

Question 4

i'm wondering why are cranial nerves not included in the central nervous system?

Accepted Answer

Mostly peripheral: Cranial nerves have their cell bodies within the central nervous system (cns), but the majority of their length/"processes" are outside the confines of the cns. The myelin covering nerves inside, vs. Outside, the CNS is different, and cranial nerves are subject to disorders common to peripheral nerves. (the cell bodies can be affected by CNS disorders as well.).

Question 5
