Anatomical terms of neuroanatomy

The palmar branch of the median nerve is a branch of the median nerve which arises at the lower part of the forearm.

Branches

It pierces the palmar carpal ligament, and divides into a lateral and a medial branch;

Clinical significance

Unlike most of the median nerve innervation of the hand, the palmar branch travels superficial to the Flexor retinaculum of the hand. Therefore, this portion of the median nerve usually remains functioning during carpal tunnel syndrome.[1]
