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: -The dorsal horn of the spinal cord is one of the grey longitudinal columns found within the spinal cord. It primarily acts as the termination of primary afferent fibers via the dorsal roots of the spinal nerves.
Detailed explanation-3: -The dorsal root is sensory and the ventral root motor; the first cervical nerve may lack the dorsal root. Oval swellings, the spinal ganglia, characterize the dorsal roots. They are formed of nerve cells that give rise to the sensory nerve fibres.
