<Tr> <Td_colspan="2"> Anatomical terminology (edit on Wikidata) </Td> </Tr> <P> The brachial artery is the major blood vessel of the (upper) arm . </P> <P> It is the continuation of the axillary artery beyond the lower margin of teres major muscle . It continues down the ventral surface of the arm until it reaches the cubital fossa at the elbow . It then divides into the radial and ulnar arteries which run down the forearm . In some individuals, the bifurcation occurs much earlier and the ulnar and radial arteries extend through the upper arm . The pulse of the brachial artery is palpable on the anterior aspect of the elbow, medial to the tendon of the biceps, and, with the use of a stethoscope and sphygmomanometer (blood pressure cuff) often used to measure the blood pressure . </P> <P> The brachial artery is closely related to the median nerve; in proximal regions, the median nerve is immediately lateral to the brachial artery . Distally, the median nerve crosses the medial side of the brachial artery and lies anterior to the elbow joint . </P>
