40
Q

coracobrachialis action

A

flexes and adducts arm at shoulder

41
Q

A

flexes arm at shoulder (minor); flexes forearm (at elbow), supinates forearm

42

medial head: elbow extension

45
Q

anconeus action

A

elbow/forearm extension

46
Q

nerves incorporated in tricep reflex

A

C7, C8

47
Q

superficial layer of anterior forearm muscles

A

pronator teres

flexor carpi radialis

palmaris longus

flexor carpi ulnaris

48
Q

middle layer of anterior forearm

A

flexor digitorum superficialis

49
Q

deep layer of anterior forearm

A

flexor pollicis longus

flexor digitorum profundus

pronator quadratus

50
Q

innervation of anterior forearm

A

all muscles are innervated by the median nerve

except: flexor carpi ulnaris is innervated by ulnar nerve and flexor digitorum profundus is innervated 50% by median (on lateral half) and 50% by ulnar (on medial half)

51
Q

origin and insertion of superficial layer anterior forearm muscles

action

A

origin: medial epicondyle
insertion: carpals and metacarpals

all those that cross the wrist flex wrist and ab or adduct the wrist depending on their insertion

pronator teres does not cross the wrist, it inserts on lateral radius and pronates the forearm/hand

52
Q

middle layer of anterior forearm origin and insertion and action

A

(only muscle is the flexor digitorum superficialis)

origin: medial epicondyle and proximal radius
insertion: middle phalanges of digits 2-5
action: flexes digits at proximal inter-phalangeal (PIP) joint

53
Q

deep layer of the anterior forearm origin, insertion, and action

A

origin: radius, ulna and interosseous membrane
insertion: distal phalanges
action: flexor pollicis longus and flexor digitorum profundus flex the digits at distal inter-phalangela (DIP) joint

pronator quadratus inserts on the distal radius and therefore pronates the forearm and hand

54
Q

list muscles in superficial posterior forearm lateral to medial

A

brachioradialis

extensor carpi radialis longus

extensor carpi radialis brevis

extensor digitorum

extensor digiti minimi

extensor carpi ulnaris

55
Q

list deep muscles in posterior forearm lateral to medial

A

supinator

abductor pollicis longus

extensor pollicis brevis

extensor pollicis longus

extensor indicis

56
Q

innervation of posterior forearm

A

radial nerve

57
Q

origin, insertion, and action of superficial layer posterior forearm

A

origin: lateral epicondyle
insertion: carpals and metacarpals

those crossing wrist joint extend the wrist and ad or abduct depending on location

extensor digitorum and digiti minimi extend the fingers

brachioradialis insters on styloid process of radius and flexes the forearm

58
Q

wrist drop/saturday night palsy

A

radial nerve/posterior cord lesion due to fracture at radial groove of humerus, or draping arm over bed and temporarily compressing posterior cord

59
Q

originn insertion, and action of deep layer posterior forearm muscles

A

origin: radius, ulna, and interosseus membrane
insertion: metacarpals or phalanges of hand
action: move digits in name of muscle

supinator inserts on lateral radius and supinates the forearm and hand

60

opponens pollicis

abductor pollicis brevis

flexor pollivis brevis

median nerve

61
Q

list hypothenar muscles of hand and innervation

A

opponens digiti minimi

abductor digiti minimi

flexor digiti minimi

innervation: ulnar nerve

62
Q

adductor pollicis innervation

A

ulnar nerve

63
Q

list muscles in hand that are inervated by median nerve

A

lumbircals

opponens pollicis

abductor pollicis brevis

flexor pollicis brevis

(LOAF)

64
Q

action of lumbricals

A

flexion of meacarpophalangeal joint (MCP)

exten interphalangeal joints (IP)

65
Q

dorsal interossei action

A

abduct (DAB) digits 2-5

66
Q
