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.
Cistern of lateral cerebral fossa. It is situated in the fissure between the frontal and temporal lobes. It contains: The middle cerebral artery; The middle cerebral veins; The fronto-orbital veins; Collaterals to the basal vein; Cistern of lamina terminalis. It is situated just rostral to the third ventricle. It contains:
(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. (b) the deep middle cerebral vein (deep Sylvian vein), which receives tributaries from the insula and neighboring gyri, and runs in the lower part of the lateral cerebral fissure, and (c ...
The superficial middle cerebral vein (superficial Sylvian vein) begins on the lateral surface of the hemisphere. It runs along the lateral sulcus [1] to empty into either the cavernous sinus, [1] [2] or sphenoparietal sinus. [1] It is adherent to the deep surface of the arachnoid mater bridging the lateral sulcus. It drains the adjacent cortex. [2]
Its inner surface presents the openings of the superior cerebral veins, which run, for the most part, obliquely forward, and open chiefly at the back part of the sinus, their orifices being concealed by fibrous folds; numerous fibrous bands (chordae Willisii) extend transversely across the inferior angle of the sinus; and, lastly, small ...
The internal cerebral veins are two veins included in the group of deep cerebral veins that drain the deep parts of the hemispheres; each internal cerebral vein is formed near the interventricular foramina by the union of the superior thalamostriate vein and the superior choroid vein.
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. Arteries deliver oxygenated blood, glucose and other nutrients to the brain.
The arachnoid granulations are local outpouchings of the arachnoid mater, as well as the subarachnoid space enclosed within it, into the dural venous sinuses. The granulations exhibit a thinner stalk that penetrates through the wall of a venous sinus, and a distended head formed within the lumen of the sinus.
