Nucleus cuneatus

Nucleus cuneatus medialis, , Post-strand nucleus outer

Lies, one more hay. and one to the left. on the outside of the nucleus gracilis and slightly higher than this on the dorsal side (posterior) of the medulla oblongata . The nucleus receives filaments (fasciculus cuneatus) that mediate high-resolution mechanoreception from the upper limb and upper trunk.

The axons leaving the nucleus cross in the decussatio lemniscorum (lemnic crossing) directly across the midline and turn off upwards in the brainstem where they form the medial lemnic together with axons from the nucleus gracilis.
