From Wikipedia, the free encyclopedia. The posterior column (dorsal column) refers to the area of white matter in the middle to posterior side of the spinal cord. It is made up of the gracile fasciculus and the cuneate fasciculus and itself is part of the posterior funiculus.It is part of an ascending pathway that is important for well-localized fine touch and conscious proprioception called the posterior column-medial lemniscus pathway.t is made up of the gracile fasciculus and the cuneate fasciculus and itself is part of the posterior funiculus.

The roots combine to form the spinal nerve and then they split apart again and are now called rami (ramus for singular). The dorsal root is posterior to the ventral (front) root. The dorsal rami innervate the deep muscles of the back for motor control, such as the erector spinae and also a horizontal strip of skin for sensory input.
