Question

in the context of specialized cell structure, which of the following components of a nerve cell hardens in patients with multiple sclerosis?
○ myelin sheath
○ nucleus
○ dendrites
○ cell body

Explanation:

In multiple sclerosis, the immune system attacks the myelin sheath (the protective covering around nerve fibers), causing it to harden and disrupt nerve signal transmission. The nucleus, dendrites, and cell body are not the primary structures affected in this way.

Answer:

A. Myelin sheath
