Question

Quizplus · Accepted Answer

White matter in the spinal cord is responsible for conducting nerve impulses, with sensory information flowing up to the brain and motor information flowing down to the effectors. The gray matter of the spinal cord contains cell bodies and is responsible for processing and integrating this information. The central canal is a small channel in the center of the spinal cord filled with cerebrospinal fluid, and the anterior commissure is a bundle of nerve fibers connecting the two halves of the spinal cord. The cauda equina refers to the group of nerves that extend from the bottom of the spinal cord and resemble a horse's tail. None of these structures serve as the highway for nerve impulse conduction in the spinal cord.
