posterior funiculus

The portion of the medulla spinalis which lies between this and the posterior median sulcus is named the posterior funiculus.

The posterior part of the medulla between the posterior median sulcus and the posterolateral sulcus contains tracts that enter it from the posterior funiculus of the spinal cord.

Dorsal radiculopathy which is secondary ascending degeneration of the posterior funiculus may also occur due to malignant cells collecting or a presence of tumor which cause compression of the nerve.
