Thoracoacromial artery

The thoracoacromial artery (acromiothoracic artery; thoracic axis) is a short trunk, which arises from the forepart of the axillary artery

Axillary artery

In human anatomy, the axillary artery is a large blood vessel that conveys oxygenated blood to the lateral aspect of the thorax, the axilla and the upper limb....
, its origin being generally overlapped by the upper edge of the Pectoralis minor.

Branches

Projecting forward to the upper border of the Pectoralis minor, it pierces the coracoclavicular fascia and divides into four branches—pectoral, acromial, clavicular, and deltoid.

Branch	Description >- \| Pectoral Pectoral Pectoral, from the Latin pectoralis , "pertaining to the breast/chest", can refer to:* Pectoral cross, a cross worn on the chest* a decorative, usually jeweled version of a gorget... branch	Descends between the two Pectorales, and is distributed to them and to the mamma Mamma Mamma has several meanings:* A Mother, biological or social female parent of a child or offspring.* The Latin term for Breasts, the upper ventral region of an animal's torso, particularly that of mammals, including human beings... , anastomosing with the intercostal branches of the internal mammary and with the lateral thoracic. \|- \| Acromial branch	Runs lateralward over the coracoid Coracoid The coracoid Process is a small hook-like structure on the lateral edge of the superior anterior portion of the scapula. Pointing laterally forward, it, together with the acromion, serves to stabilize the Glenohumeral joint.... process and under the Deltoideus, to which it gives branches; it then pierces that muscle and ends on the acromion in an arterial network formed by branches from the transverse scapular, thoracoacromial, and posterior humeral circumflex arteries. \|- \| Clavicular branch	Runs upward and medialward to the sternoclavicular joint, supplying this articulation, and the Subclavius. \|- \| Deltoid Deltoid Deltoid can refer to:* The deltoid muscle, a muscle in the shoulder* Kite , also known as a deltoid, a type of quadrilateral* A deltoid curve, a three-sided hypocycloid... (humeral) branch	Often arising with the acromial, it crosses over the Pectoralis minor and passes in the same groove as the cephalic vein Cephalic vein In human anatomy, the cephalic vein is a superficial vein of the upper limb.It communicates with the basilic vein via the median cubital vein at the Elbow-joint and is located in the superficial fascia along the anterolateral surface of the biceps brachii muscle.... , between the Pectoralis major and Deltoideus, and gives branches to both muscles.

Mnemonic

Mnemonics used to remember the four branches are "Cadavers Are Dead People" or "ABCD" where Breast (pectoral).
