  1. abductor digiti minimi
    • origin = pisiform
    • insertion = medial surface of base of proximal phalanx of pinky finger
    • innervation = deep branch of ulnar n. (C8, T1)
    • action = abduct pinky finger; assist in flexion of it's proximal phalanx
    • blood supply = ulnar a., dorsal venous network of vv.
  2. flexor digiti minimi brevis
    • origin = hook of hamate, flexor retinaculum
    • insertion = medial surface of base of proximal phalanx of pinky finger
    • innervation = deep branch of ulnar n. (C8, T1)
    • action = flex pinky proximal phalanx of pinky
    • blood supply = ulnar a. dorsal venous network of vv.
  3. opponens digiti minimi
    • origin = hook of hamate, flexor retinaculum
    • insertion = medial surface of pinky metacarpal
    • innervation = deep branch of ulnar n. (C8, T1)
    • action = bring pinky metacarpal anteriorly, and rotate it, bringing pinky into opposition with the thumb
    • blood supply = ulnar a. dorsal venous network of vv.
  4. abductor pollicus brevis
    • origin = flexor retinaculum and tubercles of scaphoid and trapezium
    • insertion = lateral surface of base of thumb's proximal phalanx
    • innervation = recurrent branch of median n. (C8, T1)
    • action = abduct thumb, helps oppose it
    • blood supply = radial a. dorsal venous network of vv.
  5. flexor pollicus brevis
    • origin = flexor retinaculum and tubercles of scaphoid and trapezium
    • insertion = lateral surface of base of thumb's proximal phalanx
    • innervation = recurrent brach of median n. (C8, T1)
    • action = flex thumb at proximal phalanx
  6. opponens pollicus
    • origin = flexor retinaculum and tubercles of scaphoid and trapezium
    • insertion = lateral border of thumb's metacarpal
    • innervation = recurrent branch of median n. (C8, T1)
    • action = oppose the thumb; draws metacarpal anteriorly and medially towards the palm of the hand
    • blood supply = radial a. dorsal venous network of vv.
  7. adductor pollicis
    • origin oblique head = base of 2nd, and 3rd finger's metacarpals, capatate and adjacent carpals
    • origin transverse head = anterior surface of 3rd finger's metacarpal
    • insertion = medial surface of base of thumb's proximal phalanx
    • innervation = deep branch of ulnar n. (C8, T1)
    • blood supply = radial a. dorsal venous network of vv.
