Question

Quizplus · Accepted Answer

The white matter of the spinal cord contains both myelinated and unmyelinated nerve fibers. Myelinated fibers appear white due to the insulating nature of the myelin sheath, hence the term "white matter". Unmyelinated fibers appear gray and are found in both white and gray matter. Therefore, choice C is the best answer. Choices A and D are incorrect because they exclude either myelinated or unmyelinated fibers, and choice B is incorrect because it suggests that soma (cell bodies) are present in the white matter, which is not the case.
