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

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.

Beneath the clavicle, plexus cords are distributed around the axillary artery and are positioned medially, laterally and posteriorly around the vessel.
2A) both lateral roots arose lateral to the 1st part of the axillary artery and passed lateral to the 2nd part of the axillary artery to form the MN lateral to the 3rd part of the axillary artery.
Samta et al reported that the third part of axillary artery gave rise to a common trunk, which branched into subscapular artery, profunda brachii and circumflex humeral arteries, and also Alar branches arose from the second part of axillary artery.
In the second case, a common trunk from the second part of the axillary artery contained the thoracoacromial, lateral thoracic, subscapular, and posterior circumflex humeral arteries.
The Axillary artery branching pattern was normal on the left side.
Obviously, this data produced represents a contribution to the literature and should be analyzed in the scientific context of axillary artery branching.
In a standard textbook (9) the term" Vasa Aberrentia" has been used to describe a long vessel that connects the brachial artery with the axillary artery or Radial artery.
It is not uncommon to find variations in the branching pattern of axillary artery. Many of its branches may arise by a common trunk or a branch of the named artery may arise separately (Hollinshead, 1958).
Axillary artery is the direct continuation of the subclavian artery from the outer border of the first rib.
