In the Disease Multiple Sclerosis, Myelin Deteriorates and is Replaced

Question

In the disease multiple sclerosis, myelin deteriorates and is replaced by ________.
A) ganglia
B) glial cells
C) neurons
D) scar tissue

Accepted Answer

In multiple sclerosis, the immune system attacks the myelin sheath that surrounds and protects nerve fibers in the central nervous system. As a result, the myelin deteriorates, leading to scar tissue formation. This process is called demyelination, and it can cause a variety of symptoms, including muscle weakness, vision loss, and cognitive dysfunction. Glial cells, neurons, and ganglia are not typically associated with the process of myelin deterioration and scar tissue formation in multiple sclerosis.
