Axillary Artery
The Axillary Artery (/ækˈsɪləri ˈɑːrtəri/; from the Latin axilla, meaning "armpit") is a large blood vessel that conveys oxygenated blood to various parts of the upper body, including the axilla (armpit) and the chest wall.
Anatomy
The Axillary Artery begins at the outer border of the first rib, becoming the Brachial Artery at the lower border of the Teres Major Muscle. It is divided into three parts by the Pectoralis Minor Muscle.
Branches
The Axillary Artery gives off several branches, including the Superior Thoracic Artery, Thoracoacromial Artery, Lateral Thoracic Artery, Subscapular Artery, and Anterior and Posterior Circumflex Humeral Arteries.
Clinical Significance
The Axillary Artery is often examined in cases of Trauma or suspected vascular disease. It can be palpated in the axilla, and its pulse can be felt, which can provide important information about the patient's circulatory status.
