Superficial Temporal Artery

Superficial Temporal Artery The structure indicated is the superficial temporal artery. The superficial temporal artery is a branch of the external carotid artery. The external carotid artery gives rise to 8 branches: Superior thyroid artery Ascending pharyngeal artery Lingual artery Facial artery Occipital artery Posterior auricular artery Maxillary artery Superficial temporal artery The maxillary artery and the superficial temporal artery are terminal branches of the external carotid artery, with the latter being the smaller of the two branches. The superficial temporal artery is often biopsied when giant-cell arteritis is suspected. The artery can be easily palpated just anterior to the …

Splenic Artery

Splenic Artery The structure indicated is the splenic artery. The splenic artery the largest of three arteries arising for the celiac trunk: Left gastric artery Common hepatic Splenic artery The celiac artery is responsible for supplying the foregut structures, arising from the abdominal aorta just below the point at which it emerges through the aortic hiatus, at the level of vertebra L1. The splenic artery takes a tortuous course along the superior aspect of the pancreas to enter the hilum of the spleen. Along its course, it gives off several branches supplying the neck, body and tail of the pancreas. …

Posterior Communicating Artery

Posterior Communicating Artery The structure indicated is the posterior communicating artery of the circle of Willis. It is one of the blood vessels which contributes to the arterial Circle of Willis – an anastomosis of arterial vessels located on the base of the brain, consisting of the following arteries: Anterior cerebral artery Anterior communicating artery Internal carotid artery Posterior cerebral artery Posterior communicating artery The posterior communicating artery connects the three cerebral arteries on the same side. It connects to the terminal part of the internal carotid artery before it bifurcates into the anterior cerebral artery and the middle cerebral …

Right Subclavian Artery

Right Subclavian Artery The structure indicated is the right subclavian artery. The subclavian arteries are located under (“sub”) the clavicle (“clavian”) and receive blood from the aortic arch. The subclavian arteries supply the arms, with some branches that extend to supply the head. The branches of the aortic arch are: Brachiocephalic artery Left common carotid artery Left subclavian artery The left subclavian artery comes directly off the arch of the aorta, whereas on the right side of the body, the brachiocephalic artery splits, giving rise to the right subclavian artery, and the right common carotid artery. The subclavian artery becomes …

Left Anterior Descending Artery

Left Anterior Descending Artery The structure indicated is the left anterior descending artery (also known as the anterior interventricular artery). The left anterior descending artery is one of the coronary arteries which supplies the anterior and lateral parts of the myocardium and the interventricular septum. It is responsible for approximately 45-55% of the left ventricles blood supply. The left coronary artery arises from the left aortic sinus of the ascending aorta. The left coronary artery has two terminal branches: Left anterior descending (LAD)/anterior interventricular Circumflex branch The left anterior descending artery itself has two different types of branches Septal branches …

Anterior Communicating Artery

Anterior Communicating Artery The structure indicated is the anterior communicating artery. The anterior communicating artery connects the left cerebral artery to the right cerebral artery. It is one of the blood vessels which contributes to the arterial Circle of Willis – an anastomosis of arterial vessels located on the base of the brain, consisting of the following arteries: Anterior cerebral artery Anterior communicating artery Internal carotid artery Posterior cerebral artery Posterior communicating artery The anterior cerebral artery also gives rise to small collateral vessels which supply the frontal lobes and basal forebrain. This vessel is a common site for the …
