ax·il·lar·y ar·ter·y

[TA]
the continuation of the subclavian artery after it crosses the first rib to enter the axilla; it becomes the brachial artery on passing the inferior border of the teres major muscle. It is accompanied by the cords of the brachial plexus and is enclosed with them and the axillary vein in the axillary sheath as it traverses the axilla. Three parts of the axillary artery are described: (1) proximal, (2) posterior, and (3) distal to the pectoralis minor muscle. Branches: first part-superior thoracic artery; second part-thoracoacromial arterial trunk, lateral thoracic artery; third part-subscapular artery, anterior and posterior humeral circumflex arteries.
Synonym(s): arteria axillaris [TA]

axillary artery

Etymology: L, axilla, wing
one of a pair of continuations of the subclavian arteries that starts at the outer border of the first rib and ends at the distal border of the teres major, where it becomes the brachial artery. It has three parts and six branches, supplying various chest and arm muscles.

axillary artery

The continuation of the subclavian artery beyond the lateral border of the first rib; its name changes to the brachial artery when it passes the lower border of the tendon of the teres major muscle. Its branches (from medial to lateral) are the supreme (superior) thoracic, thoracoacromial, lateral thoracic, subscapular, and anterior and posterior circumflex humeral arteries.
