Thebrachial artery is the majorblood vessel of the (upper) arm. It is the continuation of theaxillary artery beyond the lower margin ofteres major muscle. It continues down theventral surface of the arm until it reaches thecubital fossa at theelbow. It then divides into theradial andulnararteries which run down theforearm.[1][2] In some individuals, the bifurcation occurs much earlier and the ulnar and radial arteries extend through the upper arm. Thepulse of the brachial artery ispalpable on the anterior aspect of the elbow, medial to thetendon of thebiceps, and, with the use of astethoscope andsphygmomanometer (blood pressure cuff), often used to measure theblood pressure.[1]
The brachial artery is closely related to themedian nerve; in proximal regions, the median nerve is immediately lateral to the brachial artery.[3] Distally, the median nerve crosses the medial side of the brachial artery and lies anterior to the elbow joint.[1][4]
The brachial artery gives rise to the following branches:[4]
It also gives rise to important anastomotic networks of the elbow and (as the axillary artery) the shoulder.
Thebiceps head is lateral to the brachial artery. The median nerve is medial to the brachial artery for most of its course.fracture of lower end of humerous may cause rupture of bracheal artery
