Learn More Trayecto La arteria circunfleja humeral anterior se origina en la cara externa de la tercera parte de la arteria axilar. Su tamaño es notablemente menor que el de la arteria circunfleja posterior. Tras su origen, la arteria circunfleja humeral anterior discurre por debajo del músculo coracobraquial y de la cabeza corta del bíceps braquial. A continuación, rodea la cara anterior del cuello del húmero. En el surco intertubercular del húmero, da origen a una rama ascendente que irriga la cabeza del húmero. Termina mediante una anastomosis con la arteria circunfleja posterior. Adobe Stock, Licensed to TeachMeSeries Ltd Fig. 1: el trayecto de la arteria circunfleja humeral anterior.

The anterior humeral circumflex artery is a branch of the axillary artery that supplies blood to the shoulder joint and surrounding muscles. It plays a crucial role in the vascularisation of the glenohumeral joint and nearby musculature. What does the anterior humeral circumflex artery supply? This artery provides blood supply to the glenohumeral joint, the head of the humerus, and several surrounding muscles, including the teres major, teres minor, deltoid, and coracobrachialis. Its contributions are vital for the proper functioning of these structures. Where does the anterior humeral circumflex artery originate? The anterior humeral circumflex artery originates from the external aspect of the third part of the axillary artery. Its size is significantly smaller compared to the posterior humeral circumflex artery. How does the anterior humeral circumflex artery travel through the shoulder region? After its origin, this artery courses beneath the coracobrachialis muscle and the short head of the biceps brachii, then wraps around the anterior aspect of the neck of the humerus. It also gives off an ascending branch that supplies the head of the humerus. What is the clinical significance of the anterior humeral circumflex artery? The anterior humeral circumflex artery is essential for the blood supply to the shoulder joint and surrounding muscles, making it significant in shoulder injuries and surgeries. Its anastomosis with the posterior humeral circumflex artery also ensures adequate blood flow in the region. Rate This Article
