Oct 30, 2023 · The circle of Willis (cerebral arterial circle or circulus arteriosus) is an anastomotic ring of arteries located at the base of the brain. This arterial anastomotic circle connects the two major arterial systems to the brain, the internal carotid arteries and the vertebrobasilar (vertebral and basilar arteries) systems. It is formed by four ...
Mar 31, 2024 · The circle of Willis (circulus arteriosus) is an anastomotic arterial ring located at the base of the brain. It provides a connection between the four main arteries that supply the brain (two vertebral and two internal carotid arteries) — protecting against ischaemia in the event of single vessel occlusion.
Jun 19, 2024 · The circle of Willis (COW) or circulus arteriosus is an arterial polygon (heptagon) formed as the internal carotid and vertebral systems anastomose around the optic chiasm and infundibulum of the pituitary stalk in the suprasellar cistern.

The circle of Willis (also called Willis' circle, loop of Willis, cerebral arterial circle, and Willis polygon) is a circulatory anastomosis that supplies blood to the brain and surrounding structures in reptiles, birds and mammals, including humans.
Jul 24, 2023 · The circle of Willis (CoW) is an anatomical structure that provides an anastomotic connection between the anterior and posterior circulations, providing collateral flow to affected brain regions in the event of arterial incompetency.
Aug 15, 2017 · 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...
