Anterior circumflex humeral artery

The anterior circumflex humeral artery emerges out of the axillary artery's lateral side. The axillary artery starts on the lateral edge of the first rib and follows the subclavian artery. It is situated close to the transverse scapular and the thoracoacromial's acromial branch. The primary task of the axillary artery is provide the chest walls and the axilla with blood vessel branches. Upon the vessel's departure of the axilla, it turns into the brachial artery. The humeral artery runs alongside latissimus dorsi's tendon in a lateral direction. It also runs below the biceps' two heads and the coracobrachialis. The artery supplies to the deltoids' lower surfaces. The coracobrachialis is a muscle that comes from the scapula's coracoid process. The primary function of the coracobrachialis is the adducting and raising of the arms. The anterior circumflex humeral artery engages in anastomosis with both the thoracoacromial arteries and the posterior circumflex. Anastomosis is a term that depicts a surgical fusion of a pair of structures. In general, it entails a connection that is established via tubular structures.
