Inferior profunda artery

Inferior profunda artery

The brachial artery. (Inferior profunda artery not labeled, but region is visible.)

The Inferior profunda artery (also known as the deep brachial artery or the profunda brachii artery) is a large vessel that arises from the brachial artery in the upper arm. It is responsible for supplying blood to the triceps brachii muscle and the humerus.

Structure

The inferior profunda artery typically arises from the brachial artery just below the lower border of the teres major muscle. It then travels downwards and backwards, running parallel to the radial nerve in the radial groove of the humerus. It gives off several branches which supply the triceps brachii muscle and the humerus.

Function

The main function of the inferior profunda artery is to supply blood to the triceps brachii muscle and the humerus. It also provides some blood supply to the elbow joint.

Clinical significance

Knowledge of the inferior profunda artery is important in surgical procedures involving the upper arm, as damage to this artery can lead to significant blood loss and potential complications.
