A

hypothenar muscle

O: flexor retinaculum
hamate
I: promximal phalanx digit #5
A: flex 5th digit
N: ulnar nerve

**more pinky

31
Q

opponens digiti minimi

A

hypothenar muscle

O: flexor retinaculum + hamate
I: metacarpal #5
A: rotate & draw metacarpal #5 forward (to bring into OPPOSITION w/ thumb)
N: ulnar nerve

  • *opponens = wrap around
  • *smallest
32
Q

palmaris brevis

A

**covers + protects ulnar artery y ulnar nerve

33
Q

thenar muscles

A

lateral (thumb) side

  • abductor pollicis brevis
  • flexor pollicis brevis
  • opponens pollicis
34
Q

abductor pollicis brevis

A

thenar muscle

O: flexor retinaculum
I: proximal phalanx of thumb
A: abduct thumb
N: median nerve

**big meaty piece of thumb side

35
Q

A: flex thumb
N: median nerve + ulnar nerve

36
Q

opponens pollicis

A

thenar muscle

I: metacarpal #1
A: opposition of thumb
N: median nerve

37
Q

brevis

A

start / end in hand

38
Q

longus

A

start in arm

OR

end in hand

39
Q

movements of thumb

A 
abduction 
adduction
extension
flexion
opposition
reposition
40
Q

A

moving thumb away from palm

41
Q

adduction

A

returning thumb to palm

42
Q

extension

A

hand flat w/ thumb away from palm

43
Q

flexion

A

thumb to base of pinky

**very similar to opposition

44
Q

opposition

A

thumb to tip of pinky

**very similar to flexion

45
Q

reposition

A

fingers touching, thumb touching side of palm

46
Q

carpal tunnel syndrome

A

decrease side of carpal tunnel, compression of median nerve

  • atrophy of thumb, causes thumb to be adducted/extended
  • inability to oppose thumb (thumb to tip of pinky)
  • problems w/ flexion + opposition
  • loss of sensation on lateral palm + lateral digits
  • numbness tingling

**must wear brace to decrease movement

47
Q

central compartment

A
  • extrinsic flexor tendon + sheaths

ulnar nerve (3-4)

**short muscles of the hand btwn tendons

49
Q

adductor compartment

A

deep to thenar compartment

- adductor pollicis

50
Q

adductor pollicis

A

adductor compartment muscle

O: metacarpal #2 – 3 + capitate + trapezoid
I: proximal phalanx of thumb
A: adduct thumb (bring thumb back to side of palm)
N: ulnar nerve

51
Q

interosseous compartment

A

located btwn metacarpals (short muscles of hand)

  • dorsal interossei (DAB)
  • palmar interossei (PAD)

**assist lumbricals

52
Q
