Volar aspect of forearm
Pronator quadratus muscle; origins of deep layer of flexor muscles
The flexor pollicis longus and flexor digitorum profundus muscles have been removed. Short ends of muscle fibres remain in the areas of origin of these muscles (6,15).

2 . Sheath of common tendon of flexor muscles (opened)
3 . Pronator quadratus muscle
4 . Radius
5 . Brachioradialis muscle (tendon of insertion)
6 . Flexor pollicis longus muscle (area of origin)
7 . Anterior interosseous nerve
8 . Left pointer: Flexor digitorum superficialis (radial head) Right pointer: Pronator teres muscle (insertion)
9 . Anterior interosseous artery
10 . Nutritive artery of radius
11 . Dorsal interosseous artery
12 . Supinator muscle
13 . Dorsal recurrent ulnar artery
14 . Ulnar artery
15 . Flexor digitorum profundus muscle (area of origin)
