Q

what bone articulations make the elbow joint?

A

1) articulation of trochlear notch of ulna, trochlea of humerus
2) articulation of head of radius, capitulum of humerus

26
Q

when are radius and ulna parallel?

A

supination / anatomical position

27
Q

when does radius cross ulna?

A

pronation

28
Q

muscles of superficial layer of flexors of forearm?

A

1) pronator teres
2) flexor carpi radialis
3) palmaris longus
4) flexor carpi ulnaris

29
Q

which muscles flex the hand

A

flexor carpi radialis, palmaris longus, flexor carpi ulnaris

30
Q

which muscle pronates hand

A

pronator teres m

pronator quadratus m (deep)

31
Q

which muscle adducts hand

A

flexor carpi ulnaris

32
Q

intermediate layer of forearm muscle(s)?

A

ONLY the flexor digitorum sperficialis m!

33
Q

why might ulnar artery be mistaken for a vein?

A

because in 3% of upper limbs, rachial artery bifurcates in the arm and therefore ulnar artery might course superficial to superficial layer of flexor muscles
if inject drug here, can severely damage hand

34
Q

what does median nerve innervation?

A

flexor compartment of forearm muscles

35
Q

what supplies deep layer of flexor muscles?

A

anterior interosseus artery

36
Q

what supplies extensor group of forearm muscles?

A

posterior interosseus artery

37
Q

deep layer of forearm flexor muscles?

A

flexor digitorum profundus, flexor pollicis longus, pronator quadratus

38
Q

innervation of flexor digitorum profundus

A

lateral half: median nerve

medial half: ulnar nerve

46
Q

what supinates the hand

A

supinator muscle!!!

47
Q

does radial nerve innervate any muscles in the hand?

A

no! because no intrinsic muscles in the dorsum of the hand

48

A

apex: clavicle, scapula, first rib
base: skin and fascia of armpit
anterior: pec major m, pec minor m, clavipectoral fascia
posterior: posterior axially fold, subscapularis m
medial: thoracic wall, serratus anterior m
lateral: intertubercular sulcus of humerus

50
Q

axillary vein forms from?

A

joining of 2 brachial veins

51
