The portion of the medulla spinalis which lies between the posterolateral sulcus and the posterior median sulcus is named the posterior funiculus. This area includes the dorsal columns (also called the posterior columns) which contains 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 other sides of the dorsal intermediate sulcus.
