<p></p> <p><b>New page</b></p><div>&#039;&#039;&#039;Basilar Artery&#039;&#039;&#039;<br /> The &#039;&#039;&#039;basilar artery&#039;&#039;&#039; is a major blood vessel in the [[human brain]]. It is formed by the union of the two [[vertebral arteries]] and provides oxygenated blood to the [[pons]], [[cerebellum]], and the posterior part of the [[cerebrum]].<br /> <br /> [[File:Blausen 0114 BrainstemAnatomy.png|thumb|alt=Blausen_0114_BrainstemAnatomy]]<br /> <br /> ==Structure==<br /> The basilar artery is a midline structure that begins at the junction of the two vertebral arteries at the level of the [[medulla oblongata]]. It travels superiorly along the anterior surface of the pons, ending at the level of the midbrain, where it bifurcates into the two [[posterior cerebral arteries]].<br /> <br /> ==Function==<br /> The basilar artery is part of the [[circle of Willis]], a circulatory anastomosis that provides collateral circulation to the brain. It gives off several branches that supply blood to various parts of the brain, including the [[anterior inferior cerebellar artery]], [[superior cerebellar artery]], and [[pontine arteries]].<br /> <br /> ==Clinical significance==<br /> Blockage of the basilar artery, known as [[basilar artery syndrome]], can lead to severe neurological deficits, including loss of consciousness, paralysis, and even death. This condition is considered a medical emergency and requires immediate treatment.<br /> <br /> ==See also==<br /> * [[Circle of Willis]]<br /> * [[Vertebral artery]]<br /> * [[Posterior cerebral artery]]<br /> <br /> ==References==<br /> &lt;references /&gt;<br /> <br /> ==External links==<br /> * [http://www.medicalimages.com/basilar-artery/ Basilar Artery] at Medical Images<br /> <br /> [[Category:Arteries of the head and neck]]<br /> [[Category:Anatomy]]<br /> <br /> {{anatomy-stub}}</div>
