Question

Which of the following statements about myelinated axons is true? a. increase surface area of the cell body b. all of the above c. help repair axonal damage d. speed up electrical signaling in the axon

Answer 1

Step-by-step explanation:

The true statement about myelinated axons is:

d. Myelinated axons speed up electrical signaling in the axon.

Myelin is a fatty substance that wraps around the axons of neurons, forming a protective sheath. This myelin sheath acts as an insulator, allowing electrical impulses to travel more efficiently and rapidly along the axon. This leads to faster conduction of signals between neurons, enhancing the speed of electrical signaling in the axon.
