Subclavian Artery

The Subclavian Artery is one of the most important arteries that provides blood supply to the neck and upper limbs. The right subclavian artery is a branch of the brachiocephalic trunk, and the left subclavian artery arises directly from the aortic arch.

The right subclavian artery, as already mentioned, is a branch of the brachiocephalic trunk, which arises from the anterior surface of the aortic arch. After exiting the chest, the right subclavian artery passes in a horizontal plane behind the collarbone, where it becomes the subclavian artery. Next, it passes under the skeletal muscle muscle, then forming the axillary artery in the area of ​​the shoulder joint.

The left subclavian artery, unlike the right, arises directly from the aortic arch in the chest. It passes along a horizontal plane in the region of the left clavicle, where it becomes the subclavian artery. Next, it passes under the skeletal muscle muscle, then forming the axillary artery in the area of ​​the shoulder joint.

The Subclavian Artery is an important vessel that supplies blood to the neck and upper limbs, as well as the brain and chest. It is the source of many important branches, such as the internal mammary artery, the posterior and anterior jugular arteries, and the superior cervical artery.

Disruption of blood supply through the Subclavian artery can lead to various diseases, such as ischemic stroke, osteochondrosis of the cervical spine, aneurysm, etc.

Thus, the subclavian artery is an important blood vessel that provides blood supply to the neck and upper limbs, as well as the brain and chest. Knowledge of its anatomy and functions is important for the diagnosis and treatment of various diseases.



The subclavian artery is a large artery in the human body that supplies blood to the neck and upper limbs. It is a branch of the brachiocephalic artery and passes through the subclavian cavity.

The right subclavian artery is formed from the brachiocephalic branch of the artery located at the level of the second rib. It passes through the front of the neck and reaches the shoulder. The left subclavian artery arises directly from the aortic arch and passes through the back of the neck.

The subclavian artery is of great importance for blood circulation in the upper limb. It supplies blood to the head, neck and shoulder area. In addition, it plays an important role in the metabolism between blood and tissues.

Subclavian artery disease can impair the blood supply to the upper limb and cause various symptoms such as pain, numbness and weakness. In such cases, it is necessary to consult a doctor for diagnosis and treatment.

In conclusion, the subclavian artery is an important element of the circulatory system in the human body. Its functions and importance for the health of the upper limb should be well known to every person.



Subclavian Artery: Anatomy and Normal Variations

The subclavian artery is one of the large branches of the aortic arch and is a continuation of the first (descending) segment of the descending aorta. At its articulation with the spine, it passes under the sternocleidomastoid muscle, arching outward in men and inward in women and children. The relationship of the lower border of the subclavian artery with the transverse processes of the vertebrae differs at different levels. On the lower cervical and I-III thoracic vertebrae, its inferior cervical groove passes through or behind the transverse processes. In the upper and middle thirds of the thoracic region it is located under the transverse processes, and in the upper part of the X thoracic vertebra - behind them. At the level of the II-IV lumbar vertebrae, the subclavian groove is absent.
