One of the dorsal column nuclei
, the cuneate nucleus
is a wedge-shaped nucleus
in the closed part of the medulla oblongata
. It contains cells that give rise to the cuneate tubercle
, visible on the posterior aspect of the medulla. It lies laterally to the gracile nucleus
and medial to the spinal trigeminal nucleus
in the medulla.
The cuneate nucleus is part of dorsal column-medial lemniscus system
, carrying fine touch
information from the upper body (above T6, excepting the face and ear - the information from the face and ear is carried by the primary sensory trigeminal nucleus) to the thalamus
via the medial lemniscus.
It may be affected by vitamin E
deficiency exhibiting neuroaxonal swelling.
