The deltoid branch is one of four arteries that arises from the thoracoacromial artery. The others include the acromial, pectoral, and clavicular branches. However, the deltoid branch may also from the acromial branch of the thoracoacromial artery (Standring, 2016).
Course
The deltoid branch travels through the pectoralis minor muscle to the cephalic vein. It travels near the deltopectoral groove towards the inferior aspect of the deltoid muscle.
Branches
No named branches.
Supplied Structures
The deltoid branch supplies the deltoid and the pectoralis major muscles. Additionally, it may contribute to the vascular supply of the proximal biceps brachii muscle (Standring, 2016).
