The gray matter of the spinal cord is shaped like a letter "H" when viewed in cross-section. This gray matter contains neurons that receive and process sensory information as well as neurons that control movement. The white matter surrounds the gray matter and contains axons that transmit information up and down the spinal cord. The junction of the dorsal and ventral roots is where sensory and motor neurons enter and exit the spinal cord, and the pattern of the ascending tracts refers to the specific pathways that transmit sensory information up to the brain.
