Arteria Axillaris, also known as the axillary artery, is a crucial blood vessel that supplies the upper limb muscles and shoulder joint with oxygen and nutrients. However, there are several other synonyms used to describe this artery. These include "brachial artery," which extends from the shoulder to the elbow, and "subclavian artery," which originates from the aorta and supplies the upper extremities and chest. Other synonyms for Arteria Axillaris include "axillary brachial artery," "brachiocephalic artery," and "thoracoacromial artery." These terms are often used interchangeably in medical literature and anatomy textbooks to describe the same blood vessel.
