What is the major artery located in the arm?

The major artery located in the arm is the brachial artery. It is the main vessel supplying blood to the arm and forms a continuation of the axillary artery as it travels past the teres major muscle. The brachial artery runs down the upper arm, branching into the radial and ulnar arteries at the elbow to supply the forearm and hand with blood.

The radial and ulnar arteries are significant as well, but they are branches of the brachial artery rather than the main artery itself. The femoral artery is located in the thigh, supplying blood to the lower extremity, and is not associated with the arm at all. Thus, the brachial artery is recognized as the primary artery in the arm, reflecting its critical role in providing blood flow to the upper limb.
