This section passes through part of the hamate (23, 28), capitate (20), trapezoid (17), and the trapezium (9). The styloid process of the third metacarpal (15) can also be distinguished.

The transverse carpal ligament (32) contains the tendons of flexor digitorum superficialis (29) and profundus (25) and flexor pollicis longus (2) in addition to the median nerve (1) within the carpal tunnel. The ulnar nerve (28) and flexor carpi radialis (6) have their own fibroosseous tunnels.

Three hypothenar muscles can be identified: opponens digiti minimi (30), abductor digiti minimi (27), and flexor digiti minimi (26).

The cephalic vein (12) is surrounded by a hematoma.
