Document Summary

All blood in the arm comes through the subclavian artery which passes under the clavicle becoming the axillary artery. The first branch off the axillary artery is the posterior humeral circumflex which runs with the axillary nerve. The axillary artery continues down the arm and becomes the brachial artery once it passes teres minor. Brachial artery runs with the musculocutaneus nerve. Almost immediately after becoming the brachial artery it divides into the radial artery and ulnar artery at the cubital fossa, each of which runs with the identically named nerve. Venous return is nearly identical with these differences: The cephalic vein on lateral side of arm collects blood from the hand and antebrachium which it then dumps into the axillary vein. The basilic vein on medial side of arm collects blood from the hand and later has blood dumped into it from the median antebrachial vein, median cubital vein, and brachial vein.
