Thoracoacromial Artery: Key Supplier to Upper Chest and Shoulder
The carotid artery, also known as the acromiothoracic artery or thoracic axis, plays a crucial role in supplying blood to the upper chest and shoulder region. This vessel, a branch of the axillary artery, has several significant branches that serve various muscles and joints in the area.
The artery begins at the axillary artery and passes through the clavipectoral fascia, dividing into four branches. One of these is the acromial branch, which provides blood to the deltoid muscles. This branch is also known as the deltoid branch and runs alongside the cephalic vein. Another key branch is the pectoral branch, which serves both pectoral muscles. The clavicular branch, meanwhile, supplies blood to the sternoclavicular joint.
The origin of the carotid artery is covered by the pectoralis minor, a triangular and slender muscle located in the upper chest. This muscle, in turn, is supplied by the pectoral branch of the carotid artery. The entire vessel serves the skin and muscles of the upper chest and shoulder, contributing to their health and function.
The carotid artery, with its various branches, is vital for the proper functioning and health of the upper chest and shoulder muscles and joints. Its role in supplying blood to these areas is essential for maintaining overall bodily health and mobility.
