Posterior horn

Posterior horn

The term posterior horn (also dorsal horn, posterior cornu, dorsal cornu) may refer to either of two separate anatomical structures within the central nervous system:

  • posterior horn of lateral ventricle in the brain, which passes forward, laterally and slightly downward, from the corpus callosum into the occiptal lobe
  • posterior horn of spinal cord, the dorsal (towards the back) grey matter section of the spinal cord that receives several types of sensory information from the body including light touch, proprioception, and vibration
