Flashcards in Vessels of the Upper Limb Deck (13):
Where does the axillary artery begin and end?
Begin - outer border of 1st rib
End - inferior border of teres major
At which level does the brachial artery split?
At the neck of the radius, into the radial and ulnar arteries.
Where does the radial artery run?
laterally in the forearm, completing in the deep palmar arch in the hand.
Where does the ulnar artery run?
Medially down the forearm (over flexor retinaculum), completing the superficial palmar arch in the hand.
What forms the superficial and deep palmar arterial arches?
Superficial - Ulnar artery + some of radial artery.
Deep - Radial artery + some of ulnar artery
What anatomical structure is formed by the carpal and palmar arches around the hand and wrist?
Collateral branches of which arteries are usually present in the elbow region?
Radial and ulnar.
Which artery often gives rise to the common interosseous artery, and what does it supply?
Ulnar artery --> common interosseous. This artery then splits into the anterior and posterior interosseous artery to supply the anterior and posterior compartment of the forearm muscles respectively.
Which compartment of the arm does the profunda brachii artery pass into?
Name the main 4 superficial veins of the upper limb.
cephalic (runs laterally), basilic (runs medially) and median cubital (communicating). Dorsal venous arch is also present.
Where do venae comitantes run?
Parallel to arteries, names include brachial and axillary vein.
Where do the axillary lymph nodes drain lymph from?
upper limb, anterior and posterior trunk.
