Lower border of teres major
True/False: teres minor is where the axillar artery ends and brachial artery begins.

3
What does the first branch of axillary artery give rise to?
Superior thoracic

Thoracoacromial trunk
Lateral thoracic artery
What are the arteries that the third part of the axillary artery give rise to?
SUBscapular artery
Anterior circumflex humeral artery
Posterior circumflex humeral artery
What does the mnemonic “screw the lawyers, save a patient” refer to?
Branches of the axillary artery: STLSAP
Superior thoracic artery
Thoracoacromial trunk
Lateral thoracic artery
SUBscapular artery
Anterior circumflex humeral artery
Posterior circumflex humeral artery
Does suprascapular artery go above or underneath the ligament?
Above
What is within the triangular space?
Circumflex scapular artery
What is within the quadrangular space?
Posterior circumflex humeral artery
What is within the triangular interval?
Deep artery of the arm
Radial nerve
What do brachial artery give rise to?
Deep brachia artery
Superior ulnar collateral artery
Inferior ulnar collateral artery
What do deep brachial artery give rise to?
Radial collateral artery
Middle collateral artery
How many branches do brachial artery give off?
3
True/False: compressing the brachial artery distal to inferior ulnar collateral artery WILL still allow blood to flow to forearm
True, because circulation is cut off below the inferior ulnar collateral, so blood can flow through ulnar collateral to the forearm
In elbow anastomosis, where does blood flow from radial collateral artery to?
Radial recurrent artery off the radial artery
Where does blood flow from middle collateral artery to in elbow anastomosis?
Interosseous recurrent artery
Where does blood flow from superior ulnar collateral artery in elbow anastomosis?
Posterior ulnar recurrent
Where does blood flow form inferior ulnar collateral artery in elbow anastomosis?
Anterior ulnar recurrent
True/False: Superior ulnar collateral artery make connection with Anterior ulnar recurrent at the forearm.
FALSE; SUPERIOR ulnar collateral artery makes connection with POSTERIOR ulnar recurrent, while Inferior ulnar collateral artery makes connection with Anterior ulnar recurrent
What are the branches of ulnar artery?
Anterior and posterior ulnar recurrent arteries
Common interosseous artery
What does the common interosseous artery branch of into?
Anterior, posterior and recurrent interosseous arteries
What is/are the branch(es) of radial artery?
radial recurrent artery
What soft tissue structure protects the brachial artery at the cubital fossa?
Biceps aponeurosis and tendon
What are the structures underneath the biceps aponeurosis?
From lateral to medial: TAN
Biceps Tendon
Brachial Artery
Median Nerve
True/False: ulnar artery is posterior to the flexor retinaculum
False; ulnar artery is SUPERFICIAL to the flexor retinaculum
Ulnar artery feeds into which arterial structures in the hand?
Mostly superficial palmer arch
Some deep palmer arch (deep ulnar branch)
Radial artery feeds into which arterial structures in the hand?
Some superficial palmer arch
Most deep dorsal circulation and deep palmer arch (deep branch)
What is the course of arterial blood flow in palmar hand?
Superficial palmar arch gives off common palmar arteries and that will branch into proper digital arteries
What is the course of arterial blood flow in deep palmar?
Deep radial to form deep palmar arch and it will let off palmar metacarpal arteries
Palmar metacarpal arteries join common palmar arteries to form proper digital arteries
What gives rise to common palmar arteries?
Superficial palmar arch
True/False: radial pulse can be felt in anatomical snuffbox
True
What is the arterial circulation in dorsal hand?
Mostly from radial artery
Radial artery form dorsal carpal arch and it will let off dorsal metacarpal arteries and then digital arteries
Which arch courses more proximally: superficial or deep palmar arches
deep
True/False: deep veins follow arteries
True
True/False: superficial veins follow arteries
False; they don’t follow arteries
True/false: there is such a thing called brachial vein
False; there isn’t. Just smaller veins in that region instead of a “brachial” vein
Cephalic vein is medial or lateral?
Lateral (thumb side)
Basilic vein is medial or lateral?
Medial
True/False: Basilic vein is much like the small saphenous vein in the legs in that it feeds into the small veins before draining into axillary vein.
True; much like small saphenous vein where it stops at the popliteal before hitting the femoral vein, basilic takes a stop before reaching the axillary vein
What is the course of cephalic vein?
Rises from the lateral side of dorsal venous network and stays superficial up the shoulder then into the axillary vein
(like great saphenous vein! Just not the same laterality)
Which vein connects cephalic and basilic veins at the cubital fossa?
Medial cubital vein
Is axillary vein medial or lateral to axillary artery
Medial
Which one is a continuation of axillar vein, basilic or cephalic vein?
Basilic. Cephalic is a branch off axillary vein
Which subclavian vein is longer and more oblique: left or right?
Left, because it has more distance to travel to get to superior vena cava
