Q

If you wanted to cut off all circulation to the arm, ligation of the axillary artery must occur where, and why

A

Ligation must be distal to the subscapular artery of the axillary artery. Due to extensive anastomosis in the scapula, ligation of axillary artery b/w thoracoacromial trunk and subscapular artery results in reversal of blood flow in the subscapular artery and continued feed of arterial blood to the brachial artery

26
Q

Dorsal carpal arch

A

Formed from the two dorsal carpal branches and the anterior interosseous artery

27
Q

Superficial palmar arch

A

Continuation of ulnar artery

29
Q
