Detailed explanation-1: -In transverse sections, the gray matter is conventionally divided into dorsal (posterior) lateral and ventral (anterior) “horns.” The neurons of the dorsal horns receive sensory information that enters the spinal cord via the dorsal roots of the spinal nerves.
Detailed explanation-2: -aka posterior horn; one of the divisions of the grey matter of the spinal cord, the dorsal horn contains interneurons that make connections within the spinal cord as well as neurons that enter ascending sensory pathways. It contains the substantia gelatinosa.
Detailed explanation-3: -aka the anterior horn of the spinal cord. One of the divisions of the grey matter of the spinal cord, the ventral horn contains cell bodies of alpha motor neurons, which innervate skeletal muscle to cause movement.
