- Abductor digiti minimi muscles (hand)
The abductor digiti minimi muscle overlies the opponens digiti minimi muscle, within the hypothenar eminence, and is one of the intrinsic muscles of the hand. Occasionally an accessory abductor digiti minimi muscle of the hand is present.
Summary
- origin: pisiform, pisohamate ligament, and tendon of flexor carpi ulnaris
- insertion: 5th proximal phalanx
- action: abducts 5th finger at metacarpophalangeal joint
- arterial supply: ulnar artery
- innervation: deep branch of ulnar nerve
