Question

Quizplus · Accepted Answer

Axons crossing from one side of the spinal cord to the other within the gray matter are found in the gray commissures, which connect the gray matter of the right and left sides of the spinal cord. The anterior, lateral, and posterior gray horns do not contain commissural fibers. White commissures, on the other hand, are composed of myelinated fibers and connect the white matter of the right and left sides of the spinal cord.
