The anterior grey column is made up of alpha motor neurons, gamma motor neurons, and small neurons thought to be interneurons.[2] The posterior grey column is divided into several of the Rexed laminae.[3] The lateral grey column is only present in the thoracic region and upper lumbar segments (T1-L2). The lateral grey column contains preganglionic cell bodies of the autonomic nervous system and sensory relay neurons.
