The posterior grey column (posterior cornu, dorsal horn, spinal dorsal horn, posterior horn, sensory horn[1]) of the spinal cord is one of the three grey columns of the spinal cord.[citation needed] It is a pronounced, dorsolaterally-oriented ridge of gray matter in either lateral half of the spinal cord. When viewed in transverse section, it is termed the posterior horn or dorsal horn.[2]
The posterior column contains the cell bodies of second-order sensory neurons and their synapses with the pseudounipolar first-order sensory neurons (whose cell bodies are located within the sensory ganglia (a.k.a. dorsal root ganglia)). It receives several types of sensory information from parts of the body (including fine touch, proprioception, and vibration) from receptors of in the skin, bones, and joints.[citation needed]
