End artery End artery An end artery (or terminal artery) is an artery that is the only supply of oxygenated blood to a portion of tissue. Arteries which do not anastomose with their neighbors are called end arteries. There is no collateral circulation present besides the end arteries. Examples of an end artery include the splenic artery that supplies the spleen and the renal artery that supplies the kidneys. End arteries are of particular interest to medicine where they supply the heart or brain because if the arteries are occluded, the tissue is completely cut off, leading to a myocardial infarction or
Lateral thoracic artery Lateral thoracic artery In human anatomy, the lateral thoracic artery (or external mammary artery) is a blood vessel that supplies oxygenated blood to the lateral structures of the thorax and breast. It originates from the axillary artery and follows the lower border of the Pectoralis minor muscle to the side of the chest, supplies the Serratus anterior muscle and the Pectoralis major muscle, and sends branches across the axilla to the axillary lymph nodes and Subscapularis muscle. It anastomoses with the internal thoracic artery, subscapular, and intercostal arteries, and with the pectoral branch of the thoracoacromial artery. In the female
