  2. 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.

    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]

  5. Cerebral circulation - Wikipedia

    en.wikipedia.org/wiki/Cerebral_circulation

    The veins puncture the relevant dural sinus, piercing the arachnoid and dura mater as bridging veins that drain their contents into the sinus. [5] The deep venous system. The deep venous system is primarily composed of traditional veins inside the deep structures of the brain, which join behind the midbrain to form the great cerebral vein (vein ...

  6. Superficial veins of the brain - Wikipedia

    en.wikipedia.org/wiki/Superficial_veins_of_the_brain

    Within the human brain, the superficial veins of the brain are those veins that are close to the surface of the brain. [1] They consist of a superior group that empties into the superior sagittal sinus and inferior sagittal sinus, and an inferior group which empties into the transverse sinuses and the cavernous sinuses.

  7. Vein - Wikipedia

    en.wikipedia.org/wiki/Vein

    There are three sizes of veins: large, medium, and small. Smaller veins are called venules, and the smallest the post-capillary venules are microscopic that make up the veins of the microcirculation. [2] Veins are often closer to the skin than arteries. Veins have less smooth muscle and connective tissue and wider internal diameters than ...

  8. Basal vein - Wikipedia

    en.wikipedia.org/wiki/Basal_vein

    The basal vein is a vein in the brain.It is formed at the anterior perforated substance by the union of (a) a small anterior cerebral vein which accompanies the anterior cerebral artery and supplies the medial surface of the frontal lobe by the fronto-basal vein.

  9. Pia mater - Wikipedia

    en.wikipedia.org/wiki/Pia_mater

    The pia mater is a thin fibrous tissue that is permeable to water and small solutes. [2] [3] The pia mater allows blood vessels to pass through and nourish the brain. The perivascular space between blood vessels and pia mater is proposed to be part of a pseudolymphatic system for the brain (glymphatic system).
