Anatomical terminology

The posterior grey column (posterior cornu, dorsal horn, spinal dorsal horn posterior 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. 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 laminae I-VI

The other laminae are located in other regions of grey matter in the spinal cord.
