Question

Quizplus · Accepted Answer

The anterior horn of gray matter contains the cell bodies of lower motor neurons, which are responsible for carrying voluntary motor impulses from the spinal cord to the muscles. The posterior horn, on the other hand, contains sensory neurons that receive and transmit sensory information from the body to the brain. The anterior and posterior columns refer to the white matter tracts in the spinal cord that contain ascending and descending axons, while the lateral horn is a small region of gray matter found only in the thoracic and lumbar segments of the spinal cord, which contains autonomic motor neurons.
