In human anatomy, the abductor digiti minimi manus (abductor minimi digiti, abductor digiti quinti, ADM) is a skeletal muscle situated on the ulnar border of the palm of the hand.

Abductor pollicis, supplied by the ulnar nerve roots C8 to T1, is an abductor of the thumb pulling it towards the palm.

The dorsal interossei of the hand are muscles that occupy the space between the metacarpals.

The flexor digiti minimi brevis is a muscle in the hand that flexes the little finger. It lies in the same plane as the abductor digiti minimi, on its radial side.

The flexor digiti minimi brevis manus is part of the hypothenar complex and is supplied by the deep branch of the ulnar nerve.

The flexor pollicis brevis is a muscle in the hand that flexes the thumb. It is one of three thenar muscles. It has both a superficial part and a deep part.
