GENERAL HISTOLOGY

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 is found at all spinal cord levels and is comprised of sensory nuclei that receive and process incoming somatosensory information. From there, ascending projections emerge to transmit the sensory information to the midbrain and diencephalon.

Detailed explanation-3: -Gray Horns The posterior horn is responsible for sensory processing. The anterior horn sends out motor signals to the skeletal muscles. The lateral horn, which is only found in the thoracic, upper lumbar, and sacral regions, is the central component of the sympathetic division of the autonomic nervous system.

Detailed explanation-4: -At the back of spinal cord the central grey matter forms two arms, each called a Dorsal Horn. The dorsal horns contain the cell bodies of sensory neurons. Two arms located at the front of the spinal cord, central grey matter are called ventral horns. They contain the cell bodies of motor neurons.
