posterior region.
The forearm － anterior region,
posterior region.

3. The arm (brachium) region
1. The anterior group
The biceps brachii, the coracobrachialis, the brachialis.
2. The posterior group
The triceps brachii.
The forearm (antebrachium) region
1. The anterior group
1) The superficial layer (6)
The brachioradialis, the pronator teres, The flexor carpi radialis,
the palmaris longus, The flexor digitorum superficialis, The
flexor carpi ulnaris.
2) The deep layer (3)

46. Flexor digitorum profundus (fdp) and superficialis (fds), flexor carpi
radialis (fcr), palmans longus (p1), and flexor carpi ulnaris (fcu). B,

fcu = flexor
carpi ulnaris;
fdp = flexor
