Antebrachium: After leaving the cubital tunnel, the ulnar nerve crosses the fibrous tendon band of the flexor carpi ulnaris on its anterior aspect. The ulnar nerve continues distally just deep to the flexor carpi ulnaris muscle until it reaches the...
Cubital tunnel: The ulnar nerve emerges from the cover of the medial head of the triceps muscle to enter into the cubital tunnel at the posterior aspect of the medial epicondyle of the humerus. This is the most common spot for the ulnar nerve to be compressed or...
Brachium: The ulnar nerve as it travels distally from the brachial plexus is found at the medial aspect of the humerus in the anterior compartment. It descends just on the anterior border of the medial intermuscular septum, where it is medial to the brachial artery....
Pathway Overview The ulnar nerve emerges from nerves C8 through T1 from the medial cord of the brachial plexus. Its course in the brachial plexus finds it bound with the other terminal branches of the brachial plexus and with the axillary artery by the axillary sheath...
Wrist: At the proximal aspect of the wrist, the median nerve can be palpated as it makes its way superficially before entering into the carpal tunnel. The median nerve can be palpated proximal to the transverse carpal ligament, just medial to the tendon for the...
