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.
The superficial cerebral veins are a group of cerebral veins in the head. This group includes the superior cerebral veins , the superficial middle cerebral vein , the inferior cerebral veins , the inferior anastomotic vein and the superior anastomotic vein .
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.
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]
The superior cerebral veins drain into the superior sagittal sinus individually. The anterior veins run at near right angles to the sinus while the posterior and larger veins are directed at oblique angles, opening into the sinus in a direction opposed to the current (anterior to posterior) of the blood contained within it.
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 superior anastomotic vein, also known as the vein of Trolard, is a superficial cerebral vein grouped with the superior cerebral veins. The vein was named after the 18th-century anatomist Jean Baptiste Paulin Trolard. The vein anastomoses with the middle cerebral vein and the superior sagittal sinus.
