The medial pectoral nerve, also called the medial anterior thoracic nerve, is a branch of the medial cord of the brachial plexus pon originating, the nerve travels together with the axillary artery and vein, being located between. The circumflex scapular artery traverses this space. It is a mixed nerve, meaning that it has both motor and sensory fibers which innervate important muscles of the upper limb and parts of the skin within the axillary Pectoralis muscle has several functions, mostly related to the movement of the scapula. An equally important artery is the facial artery, which supplies the muscles of facial expression. Along with the levator scapulae, trapezius and rhomboid muscles, the latissimus dorsi belongs to the superficial layer Lateral thoracic artery (branch of the axillary artery). The subclavian artery is a paired arterial vessel of the thorax.The right and left arteries have different origins; the left subclavian artery originates directly from the aortic arch, while the right subclavian artery originates from the brachiocephalic trunk.. Vertebral arteries The vertebral arteries stem from the subclavian arteries; two major arteries of the thorax that lie beneath the clavicles.The vertebral arteries ascend through the neck inside the transverse foramina of the cervical vertebrae, all the way to the brain.Through their course, they give off several meningeal, muscular and spinal branches for the nearby structures. The thoracic, or chest wall, consists of a skeletal framework, fascia, muscles, and neurovasculature all connected together to form a strong and protective yet flexible cage.. Thoracoacromial artery (branch of the second part of axillary artery) gives two supplying branches - pectoral and deltoid. The circumflex scapular artery traverses this space. It arises from the external carotid artery at the level of the hyoid bone. This is where the proximal end of the humerus joins with the long shaft. The medial pectoral nerve is solely a motor nerve. The cephalic vein is a superficial vein of the upper limb and it's one of the two main veins of the arm. The superior thyroid artery has several branches which include On the posterior aspect of the shaft of the humerus, profunda brachii branches into a middle and a radial collateral artery.The brachial artery gives off a superior ulnar collateral artery (about 1-2 cm below profunda brachii) and an inferior ulnar collateral artery This space allows the passage of the circumflex scapular artery and vein from the axillary region to the scapular region.
