What is the major artery of the left arm?

This comes from my A&P lab manual... "In the armpit, the subclavian artery becomes the axillary artery, which serves the upper limb." The previous answer was "brachial," which could also be a correct answer. "The brachial artery divides into the radial and ulnar arteries, which follow the same-named bones to supply the forearm and hand."
