What Is the Posterior Descending Artery? The posterior descending artery, which is also known as the posterior inter-ventricular artery, is a branch of one of the heart's main arteries. In most people, the posterior descending artery branches away from the right coronary artery, which is called right coronary artery dominance. In left coronary artery dominance, the posterior descending artery branches away from the left circumflex artery.

Ascending limb of loop of Henle The ascending limb of the loop of Henle is a direct continuation from the descending limb of loop of Henle, and one of the structures in the nephron of the kidney. The ascending limb has a thin and a thick segment.The ascending limb drains urine into the distal convoluted tubule.The thin ascending limb is found in the medulla of the kidney, and the thick ascending limb can be divided into a part that is in the renal medulla and a part that is in the renal cortex.The ascending limb is much thicker than the descending limb.he ascending limb drains urine into the distal convoluted tubule. The thin ascending limb is found in the medulla of the kidney, and the thick ascending limb can be divided into a part that is in the renal medulla and a part that is in the renal cortex.

Subclavian Artery - Regional Approach and Mnemonic 1 It branches off arteries to the larynx (inferior laryngeal artery), infrahyoid muscles and prevertebral muscles and many more smaller ones to the surrounding structures.  The ascending cervical artery is next and ascends along the phrenic nerve at the level of the fourth cervical vertebra.

Coronary Anatomy and Blood Flow Coronary Anatomy and Blood Flow. The major vessels of the coronary circulation are the left main coronary that divides into left anterior descending and circumflex branches, and the right main coronary artery. The left and right coronary arteries originate at the base of the aorta from openings called the coronary ostia located behind the aortic valve leaflets.

Management of Patients After Percutaneous Coronary Interventions The left circumflex artery travels toward the inferior surface of the heart, supplying the obtuse marginal branches. In a small percentage of persons, the circumflex artery ends as the posterior descending artery.

- A posterior STEMI occurs when the posterior area of the left ventricle, usually supplied by posterior descending artery (a branch of right coronary artery in 80% cases) is occluded by a thrombus. Isolated posterior STEMI is rare. The majority of cases it occurs with inferior STEMI or lateral STEMI.

Lateral Circumflex Femoral Artery divides into three branches: the ascending, transverse, and descending branches. The ascending branch passes over to the side of the hip, and joins a network with the end branches of the superior gluteal and deep iliac circumflex arteries. The descending branch courses downward behind the rectus femoris, and one long branch descends as far as the knee, where it joins an aspect of the popliteal artery.

Overview These connections form the anterior half (anterior circulation) of the circle of Willis. Posteriorly, the basilar artery, formed by the left and right vertebral arteries, branches into a left and right posterior cerebral artery (PCA), forming the posterior circulation. The PCAs complete the circle of Willis by joining the internal carotid system anteriorly via the posterior communicating (PCOM) arteries.

- At the superior border of the pons, the basilar artery divides to form the two posterior cerebral arteries. Before the basilar artery divides, several other arteries arise from it. These include the anterior, inferior, and posterior cerebellar arteries as well as pontine branches.ne exception to this pattern is alternating hemiplegia. This is a paralysis that can be caused by ischemic stroke and affects different structures on each side of the body. It results from a brain stem lesion that damages cranial nerve nuclei and one side of the pyramidal tract in the same area.

Anatomy and Function of the Coronary Arteries The left main coronary artery divides into branches: The left anterior descending artery, which branches off the left coronary artery and supplies blood to the front of the left side of the heart. The circumflex artery, which branches off the left coronary artery and encircles the heart muscle.

Brain Ischemia - Vascular territories The anterior choroidal artery originates from the internal carotid artery. Rarely it arises from the middle cerebral artery. The territory of the anterior choroidal artery encompasses part of the hippocampus, the posterior limb of the internal capsule and extends upwards to an area lateral to the posterior part of the cella media. The whole area is rarely involved in AChA infarcts.

Management of Patients After Percutaneous Coronary Interventions The right coronary artery gives rise to acute marginal branches and terminates as the posterior descending artery in at least 80% of the population, supplying septal perforator arteries to the posterior intraventricular septum.

Inferior Mesenteric Artery In the place of a single inferior mesenteric trunk two arteries originated from the aorta 2.6 cm apart, the inferior one located 3cm superior to the bifurcation of the aorta. The superior of the two was directed superiorly and gave rise to two branches.

Posterior communicating artery Aneurysms of the posterior communicating artery are the third most common circle of Willis aneurysm (the most common are anterior communicating artery aneurysms) and can lead to oculomotor nerve palsy.he brain is supplied with blood by the internal carotid arteries and also by the posterior cerebral arteries; the posterior communicating arteries connects the two systems. This provides redundancies or collaterals in the cerebral circulation so that, if one system is blocked or narrowed, the other can take over.

Spleen Angiogram The inferior polar artery usually gives rise to the left gastroepiploic artery, but the latter may also arise from the distal splenic or inferior terminal artery. The left gastroepiploic artery then runs along the greater curvature of the stomach.Numerous short gastric branches arise from the terminal splenic or left gastroepiploic artery to supply the gastric cardia and fundus. The splenic artery has many branches that supply the pancreatic body and tail.The first large branch is the dorsal pancreatic artery, and the second large branch is the greater pancreatic artery (or arteria pancreatica magna), which arises from the middle segment of the splenic artery.he splenic artery has many branches that supply the pancreatic body and tail.
