Brachiocephalic artery
Brachiocephalic Artery
The Brachiocephalic Artery (pronounced: brak-ee-oh-seh-fal-ik ar-ter-ee), also known as the Innominate Artery, is a major blood vessel in the upper body. It is the first branch of the aortic arch and supplies blood to the right arm, the head, and the neck.
Etymology
The term "Brachiocephalic" is derived from the Greek words "brachion" meaning arm and "kephale" meaning head, which accurately describes the areas this artery supplies.
Anatomy
The Brachiocephalic Artery originates from the aortic arch and travels upwards towards the neck. It divides into the right common carotid artery and the right subclavian artery. The right common carotid artery supplies blood to the right side of the neck and head, while the right subclavian artery supplies blood to the right arm.
