  2. 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]

  3. 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.

  4. Cerebral circulation - Wikipedia

    en.wikipedia.org/wiki/Cerebral_circulation

    The maturation of blood vessels in the brain is a critical process that occurs postnatally. [6] It involves the acquisition of key barrier and contractile properties essential for brain function. During the early postnatal phase, endothelial cells (ECs) and vascular smooth muscle cells (VSMCs) undergo significant molecular and functional changes.

  5. Circle of Willis - Wikipedia

    en.wikipedia.org/wiki/Circle_of_Willis

    Considerable anatomic variation exists in the circle of Willis, with classic anatomy seen only in about one-third of people. [4] In one common variation the proximal part of the posterior cerebral artery is narrow and its ipsilateral posterior communicating artery is large, so the internal carotid artery supplies the posterior cerebrum; this is ...

  6. Superior cerebellar artery - Wikipedia

    en.wikipedia.org/wiki/Superior_cerebellar_artery

    The arteries of the base of the brain. Superior cerebellar artery labeled near center. The temporal pole of the cerebrum and a portion of the cerebellar hemisphere have been removed on the right side (left half of diagram). Inferior aspect (viewed from below). The superior cerebellar artery supplies deep parts and superior parts of the cerebellum.

  7. 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. The pontine arteries include the paramedian arteries, the short circumferential, and the long circumferential arteries. [1] [a]

  8. Anterior cerebral artery - Wikipedia

    en.wikipedia.org/wiki/Anterior_cerebral_artery

    Arteries of the brain. Anterior cerebral artery labeled at the left (twice) The anterior cerebral artery is divided into 5 segments. Its smaller branches: the callosal (supracallosal) arteries are considered to be the A4 and A5 segments. [1] [2] A1 originates from the internal carotid artery and extends to the anterior communicating artery (AComm).

  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 ...
