Anterior circumflex artery (A. Circumflexa Humeri Anterior, PNA, BNA): anatomical overview and functions

Introduction:
The anatomy of the human body includes a complex network of blood vessels that provide oxygen and nutrients to various tissues and organs. Arteries, which play a key role in this system, are tubular structures responsible for transporting blood from the heart to peripheral tissues. In this article we will look at the anterior circumflex artery (A. Circumflexa Humeri Anterior, PNA, BNA), its anatomy and functions.

Anatomy:
The anterior humeral circumflex artery is one of the branches of the brachial artery. It originates from the posterior surface of the brachial artery in the area of ​​the shoulder joint. After its origin, it forms a twisted loop around the anterior surface of the neck of the humerus and is directed down to the shoulder joint. It then runs along the front side of the humerus, providing blood supply to the surrounding tissues and structures.

Functions:
The anterior humeral circumflex artery plays an important role in providing blood supply to the shoulder joint and its surrounding structures. It is responsible for supplying oxygen and nutrients to the muscles and tendons that are involved in movement and stabilization of the shoulder joint. In addition, the artery provides blood supply to the skin and other soft tissues in the shoulder area.

Clinical significance:
Damage to the anterior humeral circumflex artery can lead to disruption of the blood supply to the shoulder joint and surrounding tissues. This can have serious consequences, including limitation of movement, pain, and even tissue necrosis. Therefore, it is important to consider this artery when performing surgical interventions in the shoulder area to avoid damage to it.

Conclusion:
The humeral circumflex artery, anterior (A. Circumflexa Humeri Anterior, PNA, BNA), is an important anatomical structure that provides blood supply to the shoulder joint and surrounding tissues. Its functionality plays an important role in maintaining normal shoulder function. Understanding the anatomy and function of this artery is of great importance for doctors, especially in the context of surgical interventions and treatment of pathologies associated with the shoulder joint.

The artery we will discuss today is the anterior humeral artery (ANA) or anterior circumflex artery (PNA). It is one of the blood vessels that supplies blood to the shoulder girdle and upper limb.

The anterior circumflex brachial nerve (also known as the anterior brachial nerve) is an important artery that supplies blood to the muscles of the upper extremity and shoulder girdle, including the biceps, triceps, and deltoids. It originates from the brachial artery, which meets in the delta
