Posterior funiculus

The posterior funiculus of the spinal cord lies between the posterolateral and the posterior median sulcus. This area includes the posterior columns (also called the dorsal columns) of white matter which contain the fasciculus gracilis and, higher in the body, the fasciculus cuneatus, which are separated by a partition of glial cells. Histologically, these two fasciculi are on either side of the posterior intermediate sulcus.
