T2 intercostal nerve

Question 2

Biceps brachii

1) origin insertion
2) action
3) blood
4) nerve

Answer 2

1) long head: infraglenoid tubercle, short head coracoid process and attach radial tuberosity via bicipital aponeuoris
2) supinates forearm, flex forearm while supine
resist dislocation of shoulder (short head)
3) brachial artery
4) musculocutaneous

Question 3

coracobrachialis

Answer 3

1) coracoid process to humerus
2) flex and adduct arm at shoulder joint and resists shoulder dislocation
3) brachial artery
4) muscuolocutaneous

Question 4

brachialis

Answer 4

1) humerus to coronoid process and tuberosity of ulna
2) flex forearm at elbow joint
3) brachial artery
4) musculocutaneous and lateral portions may receieve radial nerve contributions

Question 5

anconeus

Answer 5

1) lateral epicondyle of humerus to lateral surface of olecrancon
2) assists triceps in extension of forearm and stabilize elbow joint. abducts ulna during pronation
3) deep brachial artery
4) radial nerve

Question 6

Triceps brachii

Answer 6

long head: infraglenoid tubercle
lateral and medial had: posteior humerus
distal attachment to end of olecranon and fascia of forearm
action: extend elbow
blood: deep brachial
nerve: radial nerve

floor cubital fossa

Answer 11

supinator and brachialis

Question 12

contents of cubital fossa

Answer 12

median nerve
bifurcation of radial and ulnar arteries

radial nerve (superficial and deep)
tendon of biceps brachii and bicepital aponeurosis

Question 13

nerve in lateral part of subcutaneous cubital fossa and what muslces is it between

Answer 13

lateral anterbrachial cutaneous nerve (off musculocutaneous nerve) peaks out between biceps brachii and brachialis muscle
