Main-Ostista artery

The basivertebral artery (lat. a. ossphenooccipitalis), or the basic vertebral artery (lat. a. basivertebralis - basivertebral) is a paired terminal branch of the spinal trunk, heading to the medulla oblongata from the base of the skull. It is a branch of the basilar artery. Between these basins there is the carotid sinus. It has no brachiocephalic continuation, but originates from large branches of the basilar vascular branch and penetrates into the skull. Both main trunks provide nutrition to the occipital part of the brain. It also forms deep sections and participates in the formation of the circle of Willis vessels.

In the body itself there is an arterial basin of the spinal column - the arterial cone that accompanies it, and the place of branching into anterior, posterior, superolateral and inferomedial branches. Among them, the first place belongs to the branch to the occipital cortex in accordance with its anatomical position. This vessel, branching from the mesenteric artery system, being a main vessel, provides nutrition to the entire posterior part of the brain. On the surface inside the skull, the peduncle of the artery becomes the basilar artery.

The lateral spinous branch extending from it, being the basilic artery, nourishes the substance of the left and right cerebral tip. Branches of the posterior and external vertebral arteries penetrate into the cavity of the pyramid
