Arteria brachialis

Arteria Brachialis is the main artery located in the upper arm of the human body. It is a major blood vessel that carries oxygenated blood from the heart to the lower arm and hand. The Arteria Brachialis begins at the level of the pectoralis major muscle and ends at the elbow where it splits into the radial artery and ulnar artery.

Anatomy

The Arteria Brachialis is a continuation of the axillary artery and begins at the lower border of the teres major muscle. It travels down the arm, running medial to the humerus bone and along the biceps brachii muscle. At the elbow, it bifurcates into the radial and ulnar arteries.

Function

The primary function of the Arteria Brachialis is to supply oxygenated blood to the muscles and tissues of the lower arm and hand. It also plays a crucial role in the circulatory system, helping to maintain blood flow and pressure throughout the body.

Clinical Significance

The Arteria Brachialis is often used in medical procedures and examinations. For example, it is the artery most commonly used to measure blood pressure. It can also be used for arterial blood gas sampling and for the insertion of a catheter during certain medical procedures.
