Blood Vessels of the Brain The middle cerebral artery is the largest branch of the internal carotid. The artery supplies a portion of the frontal lobe and the lateral surface of the temporal and parietal lobes, including the primary motor and sensory areas of the face, throat, hand and arm, and in the dominant hemisphere, the areas for speech.

Cerebral Aneurysm A cerebral aneurysm (also called an intracranial aneurysm or brain aneurysm) is a bulging, weakened area in the wall of an artery in the brain, resulting in an abnormal widening, ballooning, or bleb. Because there is a weakened spot in the aneurysm wall, there is a risk for rupture (bursting) of the aneurysm.

Aneurysm Cerebral aneurysms, also known as intracranial or brain aneurysms, occur most commonly in the anterior cerebral artery, which is part of the circle of Willis. This can cause severe strokes leading to death. The next most common sites of cerebral aneurysm occurrence are in the internal carotid artery.

Overview 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.

Blood Vessels of the Brain The vertebrobasilar arteries supply the posterior two-fifths of the cerebrum, part of the cerebellum, and the brain stem. Any decrease in the flow of blood through one of the internal carotid arteries brings about some impairment in the function of the frontal lobes. This impairment may result in numbness, weakness, or paralysis on the side of the body opposite to the obstruction of the artery.

Posterior communicating artery From Wikipedia, the free encyclopedia. In human anatomy, the left and right posterior communicating arteries are arteries at the base of the brain that form part of the circle of Willis. Each posterior communicating artery connects the three cerebral arteries of the same side.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.

Anatomy & Physiology 224 Ch21 Three branches are given off from the arch of the aorta: the brachiocephalic trunk, the left common carotid artery, and the left subclavian artery. The brachiocephalic trunk is the largest branch of the arch of the aorta and divides into the right common carotid and right subclavian arteries.

Overview The vertebrobasilar arterial system perfuses the medulla, cerebellum, pons, midbrain, thalamus, and occipital cortex. Occlusion of large vessels in this system usually leads to major disability or death. Vertebrobasilar stroke carries a mortality rate of more than 85%.

Middle cerebral artery The middle cerebral artery (MCA) is one of the three major paired arteries that supply blood to the cerebrum. The MCA arises from the internal carotid and continues into the lateral sulcus where it then branches and projects to many parts of the lateral cerebral cortex.

Right Vertebral Artery Right Vertebral Artery: The right vertebral artery is a major systemic artery that branches off from the right subclavian artery. The right vertebral artery supplies vital oxygenated blood and nutrients to the brain and cervical vertebrae.

- South Korea’s employment structure requires workers to work long hours despite low productivity, as it is more cost-effective for businesses,” Kim Jong-jin, a researcher from the Korea Labor & Society Institute, told The Korea Herald. According to OECD data, South Koreans’ labor productivity was $31.90 per hour in 2014, much lower than the OECD average of $49. It draws a stark comparison with France, where laborers work for 35 hours a week, but with productivity scores of $64 per hour.

Overview Middle cerebral artery (MCA) stroke describes the sudden onset of focal neurologic deficit resulting from brain infarction or ischemia in the territory supplied by the MCA. The MCA is by far the largest cerebral artery and is the vessel most commonly affected by cerebrovascular accident.

What You Should Know About Cerebral Aneurysms The most reliable test is called a diagnostic cerebral angiogram. In this test, the patient lies on an X-ray table. A small tube (catheter) is inserted through a blood vessel in the leg (groin) and guided into each of the blood vessels in the neck that go to the brain.

- The circle of Willis (circulus arteriosus cerebri) is an anastomotic system of arteries that sits at the base of the brain. The “circle” was named after Thomas Willis by his student Richard Lower. Willis was the author of Cerebri Anatome, a book that described and depicted this vascular ring.

Posterior communicating artery Since the cerebral arterial circle is so central in the brain, problems with it may have life-threatening consequences. The posterior communicating artery is one of the potential sites of aneurysms, which are diseased areas of an artery that are weak and bulging (sometimes resulting in rupture).

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.

- Basilar artery. The basilar artery is part of the blood supply system for the brain and central nervous system. It is formed where the two vertebral arteries join at the base of the skull. The basilar artery carries oxygenated blood to the cerebellum, brainstem, and occipital lobes.The cerebellum helps with voluntary processes such as posture, balance, coordination, and speech.nterruption of the blood flow through the basilar artery can lead to severe brain damage, organ malfunction, or even death. An aneurysm, or bulge in the artery wall, may push that portion of the brain, causing rupture and hemorrhage (bleeding).
