Which of the following is true about myelin?
It inhibits neural communication.
O It cannot be affected by illness.
It is covered by axons.
It's a fatty insulation.
It slows down neuronal operations.

Answers

Answer 1

Answer:

It's a fatty insulation.

Explanation:

"Myelin" is a fatty substance which insulates the axons of the nerve cells. Therefore, it covers the axons. This makes choice A correct and choice C incorrect.

This allows faster neural communication or hastens the transmission of signals between neurons. This makes choice A incorrect and choice E incorrect. It doesn't inhibit neural communication nor does it slow down neuronal operation; rather, it increases both speed.

Myelin can be affected by illness. An example of this is the disease called "Multiple Sclerosis," which targets the myelin sheath.
