[TA]
origin, is a continuation of the axillary beginning at the inferior border of the teres major muscle; branches, deep brachial, superior ulnar collateral, inferior ulnar collateral, muscular, and nutrient; terminates in the cubital fossa (elbow level) by bifurcating into radial and ulnar arteries.

brachial artery

the principal artery of the upper arm that is the continuation of the axillary artery. It has three branches and terminates at the bifurcation of its main trunk into the radial artery and the ulnar artery.

brachial artery

The major artery located medially in the upper arm, midway between the elbow and shoulder.

Origin
Axial artery at the inferior margin of the teres major muscle.

Termination
Splits into the radial and ulnar arteries at the cubital fossa.

Palpation
At the cubital fossa, medial to the biceps tendon.

BRACHIAL ARTERY

brachial artery

The main artery of the arm. The brachial artery is a continuation of the axillary artery and it runs on the inside (medial side) of the arm; it terminates by splitting into the radial and ulnar arteries. Its main branches include the deep brachial (profunda brachii) artery and the superior and inferior ulnar collateral arteries.
