what attaches onto the ulnar tuberosity?: brachialis muscle
what attaches to the radial tuberosity of the radius?: biceps brachii tendon
what are the 2 ligaments at the elbow joint called: radial collateral ligament
ulnar collateral ligament
contents of the cubital fossa: 1 vein, 1 artery, 1 nerve, 1 tendon:

what forms the floor of the cubital fossa: brachialis and supinator muscles
what is the annular ligament?: forms a ring around the head of the radius
what muscles does the anterior interosseus nerve (of the median nerve) supplyy?: the deep muscles for the arm:
1. LATERAL ASPECT of flexor digitorum profundus
2. flexor pollicis longus
3. pronator quadratus
what is the innervation of flexor digitorum profundus?: lateral aspect = anterior interosseus branch of median nerve

starting at the ulnar artery, list the branches: ulnar artery --> common interosseus artery --> ant. and post. interosseus arteries
if you see a vein in teh deltopectoral groove, which will it be?: the cephalic vein. This is where it pierces the deep fascia and empties into the axillary vein
where do the lateral and medial pectoral nerves come off of?: lateral pectoral nerve = lateral cord (before it gives rise to teh musculocutaneous nerve)

medial pectoral nerve = medial cord (before it gives rise to the ulnar nerve)
name one function of the pec major: adduction

what is teres minor innervated by? (NOT PEC...we're talking about TERES!): axillary nerve
which is the largest branch of the axillary artery?: subscapular artery
what is the fate of the subscapular artery?: gives off the circumflex scapulary artery which then travels through the triangular space.
where is the suprascapular artery located? and what is it a branch of?: is it located above the superior transverse ligament (suprascapular notch). It is a branch of the subclavian artery.
