Subclavian Artery

The Subclavian Artery (pronounced: sub-CLAY-vee-an AR-ter-ee) is a major artery in the human body that supplies blood to the upper limbs. The term "subclavian" is derived from Latin, with "sub" meaning under and "clavius" referring to the clavicle or collarbone, under which the artery is located.

Structure

The Subclavian Artery originates from the Aortic Arch on the left side of the body and from the Brachiocephalic Artery on the right side. It travels laterally towards the upper limb, passing over the first rib and under the clavicle. It continues as the Axillary Artery after it crosses the lateral border of the first rib.

Branches

The Subclavian Artery gives off several branches as it courses through the neck and towards the upper limb. These include the Vertebral Artery, Internal Thoracic Artery, and the Thyrocervical Trunk.

Clinical Significance

The Subclavian Artery can be involved in several medical conditions. For instance, a Subclavian Steal Syndrome can occur when there is a blockage in the Subclavian Artery proximal to the origin of the Vertebral Artery. This can lead to reversed blood flow in the Vertebral Artery, potentially causing symptoms such as dizziness and syncope.
