POSTERIOR BRANCH OF MEDIAL ANTEBRACHIAL CUTANEOUS NERVE/ ULNAR BRANCH

The ulnar branch (ramus ulnaris; posterior branch) passes obliquely downward on the medial side of the basilic vein, in front of the medial epicondyle of the humerus, to the back of the forearm, and descends on its ulnar side as far as the wrist, distributing filaments to the skin.

It communicates with the medial brachial cutaneous, the dorsal antebrachial cutaneous branch of the radial, and the dorsal branch of the ulnar.
