  2. Cerebral circulation - Wikipedia

    en.wikipedia.org/wiki/Cerebral_circulation

    Cerebral circulation is the movement of blood through a network of cerebral arteries and veins supplying the brain. The rate of cerebral blood flow in an adult human is typically 750 milliliters per minute , or about 15% of cardiac output .

  3. Circle of Willis - Wikipedia

    en.wikipedia.org/wiki/Circle_of_Willis

    The circle of Willis is a part of the cerebral circulation and is composed of the following arteries: [3] Anterior cerebral artery (left and right) at their A1 segments; Anterior communicating artery; Internal carotid artery (left and right) at its distal tip (carotid terminus) Posterior cerebral artery (left and right) at their P1 segments

  4. Cerebral arteries - Wikipedia

    en.wikipedia.org/wiki/Cerebral_arteries

    The arteries are usually divided into different segments from 1–4 or 5 to denote how far the level of the branch with the lower numbers denoting vessels closer to the source artery. Even though the arteries branching off these vessels retain some aspect of constancy in terms of size and position, a great amount of variety in topography ...

  5. Anterior cerebral artery - Wikipedia

    en.wikipedia.org/wiki/Anterior_cerebral_artery

    The two anterior cerebral arteries arise from the internal carotid artery and are part of the circle of Willis. The left and right anterior cerebral arteries are connected by the anterior communicating artery. Anterior cerebral artery syndrome refers to symptoms that follow a stroke occurring in the area normally supplied by one of the arteries.

  6. Basilar artery - Wikipedia

    en.wikipedia.org/wiki/Basilar_artery

    The basilar artery (U.K.: / ˈ b æ z. ɪ. l ə /; [1] [2] U.S.: / ˈ b æ s. ə. l ər / [3]) is one of the arteries that supplies the brain with oxygen-rich blood.. The two vertebral arteries and the basilar artery are known as the vertebral basilar system, which supplies blood to the posterior part of the circle of Willis and joins with blood supplied to the anterior part of the circle of ...

  7. Leptomeningeal collateral circulation - Wikipedia

    en.wikipedia.org/wiki/Leptomeningeal_collateral...

    The leptomeningeal collateral circulation (also known as leptomeningeal anastomoses or pial collaterals) is a network of small blood vessels in the brain that connects branches of the middle, anterior and posterior cerebral arteries (MCA, ACA, and PCA), [1] with variation in its precise anatomy between individuals. [2]

  8. Pontine arteries - Wikipedia

    en.wikipedia.org/wiki/Pontine_arteries

    The pontine arteries are a number of small arteries which come off at right angles from either side of the basilar artery and supply the pons and adjacent parts of the brain.

  9. Cerebral veins - Wikipedia

    en.wikipedia.org/wiki/Cerebral_veins

    3D model of cerebral veins. In human anatomy, the cerebral veins are blood vessels in the cerebral circulation which drain blood from the cerebrum of the human brain.They are divisible into external (superficial cerebral veins) and internal (internal cerebral veins) groups according to the outer or inner parts of the hemispheres they drain into.
