Study Notes
Median Nerve
- Root value: C5-T1
- Origin: formed by lateral and medial cords of the brachial plexus
- Branches: no branches in the axilla or the arm
- Supplies:
- Primary nerve of the anterior forearm, supplying all muscles in this compartment, except flexor carpi ulnaris (FCU) and the medial half of flexor digitorum profundus (FDP).
- Frequently co-innervates the FDP part inserting into the 3rd digit.
- Supplies the three thenar muscles, excluding the deep head of flexor pollicis brevis, and the first two lumbricals of the hand.
