|Nerve: Palmar branch of ulnar nerve|
|Superficial palmar nerves. (Deep branch of ulnar and superficial branch of ulnar labeled at center right.)|
|Latin||ramus palmaris nervi ulnaris|
|Gray's||subject #210 942|
|To||superficial branch, deep branch|
The palmar branch of the ulnar nerve arises about 5 cm above the wrist from where the ulnar nerve splits into palmar and dorsal branches.
The palmar branch represents the continuation of the ulnar nerve as it crosses the flexor retinaculum of the hand on the lateral side of the pisiform bone, medial to and a little behind the ulnar artery.
It ends by dividing into a superficial and a deep branch.
