Definition & Meaning of "axillary artery"

What is "axillary artery"?

The axillary artery is a crucial blood vessel that runs through the armpit region and supplies blood to the upper limb. It originates from the subclavian artery and continues down the arm as the brachial artery. The axillary artery gives rise to several branches that provide oxygenated blood to various structures, including the shoulder joint, muscles, and skin of the upper arm. Its role in delivering vital nutrients and oxygen makes it essential for the proper functioning of the upper extremity.
