The brachial artery is the major blood vessel of the upper arm.

Additional recommended knowledge

It is a continuation of the axillary artery and it originates from the lower margin of teres major muscle and continues down the arm, until it reaches the cubital fossa at the elbow. It then ends by dividing 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 and, with the use of a stethoscope and sphygmomanometer (blood pressure cuff) often used to measure the blood pressure.

Branches

  • Profunda brachii artery (also known as the deep brachial artery)
  • Superior ulnar collateral artery
  • Inferior ulnar collateral artery
  • Radial artery (a terminal branch)

The brachial artery has several branches along its course. These supply the muscles of the upper arm, such as biceps brachii muscle and triceps brachii muscle, and contribute to important anastomotic networks of the elbow and (as the axillary artery) the shoulder.
