NEET PG DENTAL EXAM

Detailed explanation-1: -The posterior grey column (posterior cornu, dorsal horn, spinal dorsal horn, posterior horn, sensory horn) of the spinal cord is one of the three grey columns of the spinal cord. It receives several types of sensory information from the body, including fine touch, proprioception, and vibration.

Detailed explanation-2: -The dorsal horns of the grey matter are positioned to receive signals from all areas of the body. The signals originate in nerves found in the skin, bones, or joints and travel through interneurons for immediate responses and through the dorsal column-medial lemniscus tract for more involved movement.

Detailed explanation-3: -The central gray matter contains neurons, axons and dendrites, glia, and capillaries. This region is divided into layers, or lamina, based on cytoarchitectural features; these laminae have distinct functions and projections, which have been described in detail in other references.

Detailed explanation-4: -The posterior root of the nerve carries sensory information into the posterior horn, often synapsing there. The anterior horn contains the cell bodies of somatic motor neurons, and it sends its axons out the anterior root of the spinal nerve to the muscle cells it innervates.
