Basilar Artery Anatomy

The basilar artery supplies blood to the brain and nervous system anatomy. The brainstem plays a role in regulating several vital functions including heart rate eating sleeping and breathing.

The basilar artery carries oxygenated blood to the cerebellum brainstem and occipital lobes.

Basilar artery anatomy. Basilar artery aneurysms are less common than anterior circulation aneurysms and rupture less frequently but their critical location necessitates careful evaluation. The basilar artery represents the rear posterior side of the circle of willis. Conceptual homology of vertebrobasilar and spinal arterial anatomy.

The basilar artery arises at the mid medullary level ascends vertically in a shallow medial groove on the ventral pontine surface reaches the interpeduncular cistern and divides into two posterior cerebral arteries terminal branches of the basilar artery. Rupture of a basilar artery aneurysm is typically localized to the interpeduncular cistern but may extend into the. It artery arises from the confluence of the left and right vertebral arteries at the base of the pons as they rise towards the base of the brain.

It ascends superiorly in the basilar sulcus ventral to the pons and divides at the ponto mesencephalic junction into the paired posterior cerebral arteries close to the pituitary stalk. The basilar artery is part of the posterior cerebral circulation. Arteria basilaris is a large blood vessel that is formed by the union of the two vertebral arteries.

The basilar artery arises from the confluence of the two vertebral arteries at the junction between the medulla oblongata and the pons between the vith cranial nerves. The basilar artery is formed from the union of the two vertebral arteries on either side. Two other arteries are given off from the first part of the subclavian artery the internal thoracic artery and the thyrocervical trunk.

Primarily the basilar artery delivers blood to several important brain. The two vertebral arteries and the basilar artery are sometimes together called the vertebrobasilar system which supplies blood to the posterior part of the circle of willis and joins with blood supplied to. Damage or disorder to the.

The pcas are the terminal branches. May present as a lobulated hyperattenuating structure anterior to the mid brain. Basilar artery branches anterior inferior cerebellar arteries.

In human anatomy the basilar artery is one of the arteries that supplies the brain with oxygen rich blood. Infarction in this territory usually resulting from in situ. The cerebellum helps with voluntary processes such as posture balance coordination and speech.

The basilar artery latin. The basilar artery is formed by fusion of the longitudinal neural system which in its most primitive form consists of loosely connected channels running along the undersurface of the brainstem. The vertebral arteries arise from the first part of the subclavian artery.

Traditionally it was thought that isolated superior cerebellar artery.
