Question

Quizplus · Accepted Answer

White matter refers to the areas of the central nervous system where myelinated axons are primarily located. These axons are responsible for transmitting signals between different regions of the brain and spinal cord. Therefore, option A, myelinated axons in the CNS, is the correct choice. Option B is incorrect because myelinated axons in the peripheral nervous system would be present in nerves, not white matter. Options C and D are incorrect because they describe nonmyelinated structures, which are not typically part of white matter.
