Arteries

Definition: The vessels carrying blood away from the heart.
Notes: IM GEN only; NIM as coord to indicate specific artery, as "pancreatic artery" = PANCREAS /blood supply (IM) + ARTERIES (NIM); /surg: consider also ENDARTERECTOMY; inflammation = ARTERITIS; arterial blood: index only if significant & coord BLOOD (NIM) + AR

Arteries Categories.
Aorta - The main trunk of the systemic arteries.
Arterioles - The smallest divisions of the arteries located between the muscular arteries and the capillaries.
Axillary Artery - The continuation of the subclavian artery; it distributes over the upper limb, axilla, chest and shoulder.
Basilar Artery - The artery formed by the union of the right and left vertebral arteries; it runs from the lower to the upper border of the pons, where it bifurcates into the two posterior cerebral arteries.
Brachial Artery - The continuation of the axillary artery; it branches into the radial and ulnar arteries.
Brachiocephalic Trunk - The first and largest artery branching from the aortic arch. It distributes blood to the right side of the head and neck and to the right arm.
Bronchial Arteries - Left bronchial arteries arise from the thoracic aorta, the right from the first aortic intercostal or the upper left bronchial artery; they supply the bronchi and the lower trachea.
Carotid Arteries - Either of the two principal arteries on both sides of the neck that supply blood to the head and neck; each divides into two branches, the internal carotid artery and the external carotid artery.
Celiac Artery - The arterial trunk that arises from the abdominal aorta and after a short course divides into the left gastric, common hepatic and splenic arteries.
Cerebral Arteries - The arteries supplying the cerebral cortex.
Ciliary Arteries - Three groups of arteries found in the eye which supply the iris, pupil, sclera, conjunctiva, and the muscles of the iris.
Coronary Vessels - The veins and arteries of the heart.
Epigastric Arteries - Inferior and external epigastric arteries arise from external iliac; superficial from femoral; superior from internal thoracic. They supply the abdominal muscles, diaphragm, iliac region, and groin. The inferior epigastric artery is used in coronary artery bypass grafting and myocardial revascularization.
Femoral Artery - The main artery of the thigh, a continuation of the external iliac artery.
Gastroepiploic Artery - Abdominal artery that follows the curvature of the stomach. The right gasteroepiploic artery is frequently used in coronary artery bypass grafting, myocardial revascularization, and other vascular reconstruction.
Hepatic Artery - A branch of the celiac artery that distributes to the stomach, pancreas, duodenum, liver, gallbladder, and greater omentum.
Iliac Artery - Either of two large arteries originating from the abdominal aorta; they supply blood to the pelvis, abdominal wall and legs.
Maxillary Artery - A branch of the external carotid artery which distributes to the deep structures of the face (internal maxillary) and to the side of the face and nose (external maxillary).
Meningeal Arteries - Arteries which supply the dura mater.
Mesenteric Arteries - Arteries which arise from the abdominal aorta and distribute to most of the intestines.
Ophthalmic Artery - Artery originating from the internal carotid artery and distributing to the eye, orbit and adjacent facial structures.
Popliteal Artery - The continuation of the femoral artery coursing through the popliteal fossa; it divides into the anterior and posterior tibial arteries.
Pulmonary Artery - The short wide vessel arising from the conus arteriosus of the right ventricle and conveying unaerated blood to the lungs.
Radial Artery - The direct continuation of the brachial trunk, originating at the bifurcation of the brachial artery opposite the neck of the radius. Its branches may be divided into three groups corresponding to the three regions in which the vessel is situated, the forearm, wrist, and hand.
Renal Artery - A branch of the abdominal aorta which supplies the kidneys, adrenal glands and ureters.
Retinal Artery - Central retinal artery and its branches. It arises from the ophthalmic artery, pierces the optic nerve and runs through its center, enters the eye through the porus opticus and branches to supply the retina.
Splenic Artery - The largest branch of the celiac trunk with distribution to the spleen, pancreas, stomach and greater omentum.
Subclavian Artery - Artery arising from the brachiocephalic trunk on the right side and from the arch of the aorta on the left side. It distributes to the neck, thoracic wall, spinal cord, brain, meninges, and upper limb.
Thoracic Arteries - Arteries originating from the subclavian or axillary arteries and distributing to the anterior thoracic wall, mediastinal structures, diaphragm, pectoral muscles, mammary gland and the axillary aspect of the chest wall.
Tibial Arteries - The anterior and posterior arteries created at the bifurcation of the popliteal artery. The anterior tibial artery begins at the lower border of the popliteus muscle and lies along the tibia at the distal part of the leg to surface superficially anterior to the ankle joint. Its branches are distributed throughout the leg, ankle, and foot. The posterior tibial artery begins at the lower border of the popliteus muscle, lies behind the tibia in the lower part of its course, and is found situated between the medial malleolus and the medial process of the calcaneal tuberosity. Its branches are distributed throughout the leg and foot.
Ulnar Artery - The larger of the two terminal branches of the brachial artery, beginning about one centimeter distal to the bend of the elbow. Like the RADIAL ARTERY, its branches may be divided into three groups corresponding to their locations in the forearm, wrist, and hand.
Umbilical Arteries - Either of a pair of arteries originating from the internal iliac artery and passing through the umbilical cord to carry blood from the fetus to the placenta.
Vertebral Artery - The first branch of the subclavian artery with distribution to muscles of the neck, vertebrae, spinal cord, cerebellum and interior of the cerebrum.
