Arm

Question 1

what are the parts of the anterior arm?

Answer 1

greater tubercle
lesser tubercle
trochlea
capitulum
coronoid fossa
radial fossa
styloid process
olecranon

Question 2

what is between the greater tubercle and the lesser tubercle of the humerus?
what passes on it

Answer 2

intertubercular groove aka bicipital groove

where tendon of long head of biceps brachii passes to its attachment at the supraglenoid tubercle
covered by transverse humeral ligament

Question 3

what are the parts of the posterior humerus?

what travels on it?

Answer 3

coranoid fossa

radial groove aka radial sulcus where radial nerve travels beside brachial artery

Question 4

what are the muscles and (their) actions of the anterior arm?

Answer 4

biceps brachii: flex forearm

brachialis: flex forearm
coracobrachialis: flex arm

Question 5

what is the fascia that covers the posterior arm?

Answer 5

brachial fascia which becomes the antibrachial fascia in the forearm

Question 6

what is the order of vasculature in the arm including major anatomical parts?

Answer 6

subclavian artery→axillary artery (at clavicle)→brachial artery (armpit, boundary of teres minor)→splits to ulnar + radial artery (at cubittal fossa)

Question 7

what direction does the brachial artery travel?

Answer 7

anteromedially

Question 8

what branches off brachial artery?

Answer 8

deep brachial artery (profunda brachii) to supply posterior arm

Question 9

what are the veins of the arm and their anatomical positioning?

Answer 9

1. basilic: medial superficial
2. cephalic: lateral superficial
3. medial cubital: connects basilic and cephalic veins at cubittal fossa
4. deep brachial veins: drain into axillary vein
