Anatomical terminology

The posterior grey column (posterior cornu, dorsal horn, spinal dorsal horn, posterior horn, sensory horn[1]) 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. This information is sent from receptors of the skin, bones, and joints through sensory neurons whose cell bodies lie in the dorsal root ganglion.

Anatomy

The posterior grey column is subdivided into six layers termed Rexed laminae I-VI

The other four Rexed laminae are located in the other two grey columns in the spinal cord.
