Question

The white matter of the spinal cord contains ________.

A) myelinated and unmyelinated nerve fibers
B) unmyelinated nerve fibers only
C) cell bodies
D) myelinated nerve fibers only

Answer 1

The white matter of the spinal cord contains both myelinated and unmyelinated nerve fibers.

Step-by-step explanation:

The white matter of the spinal cord contains myelinated and unmyelinated nerve fibers. White matter consists mainly of axons covered with myelin sheath. Gray matter, on the other hand, contains mainly cell bodies of neurons. Therefore, option A) myelinated and unmyelinated nerve fibers, is the correct answer.
