EspañolPOSTERIOR HORN
(Redirected from Posterior columns)
The 'posterior horn' ('posterior column', '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.
★ 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.
★ Posterior column-medial lemniscus pathway
★ Posterior horn of lateral ventricles
★ Anterior horn
