Volar aspect of forearm

Nerve supply to right pronator teres and flexor carpi radialis muscles

The humeral head (4) of the pronator teres has been divided and its fascicles separated to display branches of the median nerve and ulnar artery within the muscle. The flexor carpi radialis muscle has been retracted medially and dissected in a similar manner.

1. Vena comitans of radial artery
2. Brachioradialis muscle
3. Radial artery
4. Pronator teres muscle (humeral head)
5. Pronator teres muscle (pointer near insertion on radius)
6. Flexor digitorum superficialis
7. Median nerve
8. Muscular branch of median nerve (to both heads of pronator teres muscle)
9. Muscular branch of median nerve (to flexor carpi radialis muscle)
10. Anterior recurrent ulnar artery
11. Pronator teres muscle (ulnar head)
