The cerebellar veins are veins which drain the cerebellum. They consist of the superior cerebellar veins and the inferior cerebellar veins ( dorsal cerebellar veins ). The superior cerebellar veins drain to the straight sinus and the internal cerebral veins .
The venous drainage of the cerebrum can be separated into two subdivisions: superficial and deep. The superficial system. The superficial system is composed of dural venous sinuses, sinuses (channels) within the dura mater. The dural sinuses are therefore located on the surface of the cerebrum.
Developmental venous anomaly in the cerebellum seen on axial contrast-enhanced T1 weighted MRI A developmental venous anomaly ( DVA , formerly known as venous angioma ) is a congenital variant of the cerebral venous drainage.
They receive the blood from the superior petrosal sinuses at the base of the petrous portion of the temporal bone; they communicate with the veins of the pericranium by means of the mastoid and condyloid emissary veins; and they receive some of the inferior cerebral and inferior cerebellar veins, and some veins from the diploë.
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.
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.
CSF returns to the vascular system by entering the dural venous sinuses via arachnoid granulations. [2] These are outpouchings of the arachnoid mater into the venous sinuses around the brain, with valves to ensure one-way drainage. [2] This occurs because of a pressure difference between the arachnoid mater and venous sinuses. [3]
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.
