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 abductor pollicis longus muscle (APL) is one of the extrinsic muscles of the hand. It lies immediately below the supinator muscle and is sometimes united with it.

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

The extrinsic extensor muscles of the hand are located in the back of the forearm and have long tendons connecting them to bones in the hand, where they exert their action.
