Brachial Artery

Brachial Artery is the great arterial trunk supplying the upper extremity between the armpit and the elbow; in other words, it is the direct continuation of the axillary artery. It runs down the front and inner side of the upper arm, giving off several named branches as it proceeds, and at a point about an inch below the bend of the elbow it terminates by dividing into radial and ulnar arteries. In cases of arterial bleeding from wounds of the hand or forearm, the brachial artery may be compressed against the middle of the shaft of the humerus, just behind the inner margin of the biceps muscle.
