  2. Cerebral circulation - Wikipedia

    en.wikipedia.org/wiki/Cerebral_circulation

    Cerebral blood flow (CBF) is the blood supply to the brain in a given period of time. [8] In an adult, CBF is typically 750 millilitres per minute or 15.8 ± 5.7% of the cardiac output. [9] This equates to an average perfusion of 50 to 54 millilitres of blood per 100 grams of brain tissue per minute. [10] [11] [12]

  3. Cerebral arteries - Wikipedia

    en.wikipedia.org/wiki/Cerebral_arteries

    The cerebral arteries describe three main pairs of arteries and their branches, which perfuse the cerebrum of the brain. The three main arteries are the: Anterior cerebral artery (ACA), which supplies blood to the medial portion of the brain, including the superior parts of the frontal and anterior parietal lobes [1]

  4. Posterior communicating artery - Wikipedia

    en.wikipedia.org/wiki/Posterior_communicating_artery

    The brain is supplied with blood by the internal carotid arteries and also by the posterior cerebral arteries; the posterior communicating arteries connects the two systems. This provides redundancies or collaterals in the cerebral circulation so that, if one system is blocked or narrowed, the other can take over.

  5. Circle of Willis - Wikipedia

    en.wikipedia.org/wiki/Circle_of_Willis

    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. [1]

  6. Dural venous sinuses - Wikipedia

    en.wikipedia.org/wiki/Dural_venous_sinuses

    These sinuses play a crucial role in cerebral venous drainage. A dural venous sinus, in human anatomy, is any of the channels of a branching complex sinus network that lies between layers of the dura mater, the outermost covering of the brain, and functions to collect oxygen-depleted blood. Unlike veins, these sinuses possess no muscular coat.

  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. Ventricular system - Wikipedia

    en.wikipedia.org/wiki/Ventricular_system

    These form the ventricular system of the brain: [8] The neural stem cells of the developing brain, principally radial glial cells, line the developing ventricular system in a transient zone called the ventricular zone. [9] The prosencephalon divides into the telencephalon, which forms the cortex of the developed brain, and the diencephalon.

  9. Anterior inferior cerebellar artery - Wikipedia

    en.wikipedia.org/wiki/Anterior_inferior...

    Occlusion of AICA is considered rare, but generally results in a lateral pontine syndrome, also known as AICA syndrome.The symptoms include sudden onset of vertigo, vomiting, nystagmus, dysarthria, falling to the side of the lesion (due to damage to vestibular nuclei), and a variety of same-side features including hemiataxia, loss of all types of sensation of the face (due to damage to the ...
