The posterior horn (posterior column, posterior cornu, dorsal horn, spinal dorsal horn) of the spinal cord is dorsal (more towards the back) to the anterior horn. 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 that synapse in the dorsal root ganglion.
[edit] Anatomy
The posterior grey horn is subdivided into these laminae. Below are several named examples of each lamina.
- Marginal lamina (Lamina I)
- Substantia gelatinosa (Lamina II)
- Nucleus proprius (Laminae III,IV,V)
- Column of Clarke (Lamina VII)
The other laminae are located in other regions of grey matter in the spinal cord.
