Damaged nerve fibers in the peripheral nervous system can repair themselves because they are coated with __________,which forms a protective tunnel around the nerve fibers.
A)glial
B)soma
C)myelin
D)neurilemma

Question

Quizplus · Accepted Answer

The protective tunnel around the nerve fibers is known as the neurilemma, which is formed by the Schwann cells. The neurilemma allows damaged nerve fibers in the peripheral nervous system to repair themselves by providing a pathway for new axonal growth. The other options, glial cells and soma, do not provide the necessary protective layer for nerve fibers, and myelin is also important for nerve function but does not directly aid in nerve fiber repair.
