|Posterior horn of spinal cord|
|Cross section of the spinal cord. The posterior horn is the upper protrusion of grey matter, labeled with "2"|
|Latin||cornu posterius medullae spinalis|
|Gray's||subject #185 753|
The posterior horn (posterior cornu, dorsal horn, spinal dorsal horn) of the spinal cord is the dorsal (more towards the back) grey matter of the spinal cord. It receives several types of sensory information from the body, including light 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.
The posterior grey horn is subdivided into these laminae. Below are several named examples of each lamina.
The other laminae are located in other regions of grey matter in the spinal cord.
- Anterior horn
- Posterior column-medial lemniscus pathway
- Posterior horn of lateral ventricles
- Wide dynamic range neuron
