Volar aspect of forearm
Nerve supply to flexor digitorum profundus muscle; volar interosseous artery and nerve
The flexor pollicis longus muscle has been retracted laterally to reveal the muscular branches of the interosseous nerve which supply the medial part of the muscle. Nerves to the flexor digitorum profundus have been exposed, particularly to that part of the muscle which inserts on the index finger.
1 . Anterior interosseous nerve
2 . Anterior interosseous artery
3 . Anastomotic loop between two muscular branches of anterior interosseous nerve
4 . Radius
5 . Flexor pollicis longus muscle (retracted laterally)
6 . Pronator teres muscle (insertion)
7 . Muscular branch anterior interosseous nerve (to flexor pollicis longus muscle)
8 . Median artery (large)
9 . Ulnar artery
10 . Dorsal interosseous artery
11 . Supinator muscle
12 . Muscular branch ulnar artery
13 . Ulnar artery (proximal part)
14 . Flexor digitorum profundus muscle (to digit II)
