GENERAL HISTOLOGY

Detailed explanation-1: -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-2: -one of the divisions of the grey matter of the spinal cord, the posterior 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: -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-4: -Spinal gray matter is butterfly-shaped. It extends from the ependymal cells lining the central canal to the surrounding white matter. Spinal gray matter is divided bilaterally into dorsal horn, intermediate substance, and ventral horn.

Detailed explanation-5: -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.
