The superior cerebellar veins pass partly forward and medialward, across the superior cerebellar vermis.They end in the straight sinus, [1] and the internal cerebral veins, partly lateralward to the transverse and superior petrosal sinuses.
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 of Galen). This vein merges with the inferior sagittal sinus to form the straight sinus which then joins the superficial venous system mentioned above at the confluence ...
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.
Cranial venous outflow obstruction, also referred to as impaired cranial venous outflow, impaired cerebral venous outflow, cerebral venous impairment is a vascular disorder that involves the impairment of venous drainage from the cerebral veins of the human brain. [1] [2] The cause of cranial venous outflow obstruction is not fully understood.
The medial branch continues backward to the notch between the two hemispheres of the cerebellum; while the lateral supplies the under surface of the cerebellum, as far as its lateral border, where it anastomoses with the anterior inferior cerebellar and the superior cerebellar branches of the basilar artery.
When it arrives at the upper surface of the cerebellum, it divides into branches which ramify in the pia mater and anastomose with those of the anterior inferior cerebellar arteries and the posterior inferior cerebellar arteries. Several branches are given to the pineal body, the anterior medullary velum, and the tela chorioidea of the third ...
The falx cerebri is a strong, crescent-shaped sheet of dura mater lying in the sagittal plane between the two cerebral hemispheres. [3] It is one of four dural partitions of the brain along with the falx cerebelli, tentorium cerebelli, and diaphragma sellae; it is formed through invagination of the dura mater into the longitudinal fissure between the cerebral hemispheres.
