This video provides a walkthrough of the venous drainage of the brain, including the superficial veins of the cerebral cortex and the dural venous sinuses. Y.
Venous Drainage of the Brain Anatomy Geeky Medics
Drainage of the inferior and medial surfaces occur through the straight sinus to the great cerebral vein (of Galen) to the internal cerebral vein and choroid plexus vein, thalamostriate vein and veins of septum pellucidum 2.
Venous Drenage Of Brain Kypho
All venous drainage occurs through dural venous sinuses that drain toward the neck veins. The walls of dural venous sinuses are also home to meningeal lymphatic vessels ( 7, 8 ), with a role in the drainage of CSF.
Emergency Medicine EducationCerebral Venous Thrombosis Pearls and Pitfalls
The venous drainage of the brain, i.e. the cerebrum, brainstem and cerebellum, is highly complex and specialised. Specific attention to the anatomy of the veins located in the brain is important for students, as unlike much of the rest of the body, venous drainage does not generally follow arterial supply in this region.

The venous drainage of the cerebrum can be separated into two subdivisions: superficial and deep.. Cerebral blood flow (CBF) is the blood supply to the brain in a given period of time. In an adult, CBF is typically 750 millilitres per minute or 15.8 ± 5.7% of the cardiac output.
Cerebral Veins by KARCEN on DeviantArt
The cerebral veins drain the brain parenchyma and are located in the subarachnoid space. They pierce the meninges and drain further into the cranial venous sinuses. The cerebral veins lack muscular tissue and valves. The cerebral venous system can be divided into: superficial (cortical) cerebral veins deep (subependymal) cerebral veins
Venous Drainage of the CNS Cerebrum TeachMeAnatomy
Early Venous Phase: Surface cortical veins are opacified early in the venous phase. The lateral (red) and medial (blue) superior hemisphere surface vessels are well seen, as is the superficial sylvian venous system (purple) draining into the inferior temporal vein (pink), which is the dominant venous drainage in this hemisphere.

Dural Venous Sinuses Craniosacral therapy, Medical anatomy, Neurology
Venous drainage of the brain and meninges: Supplied by the dural venous sinuses. Venous drainage of the scalp and face: Drained by veins synonymous with the arteries of the face and scalp. These empty into the internal and external jugular veins. Venous drainage of the neck: Carried out by the anterior jugular veins.
Drenaje venoso del cerebro Anatomía My Star Idea
Delicate venous drainage from the cerebral hemispheres emerges from the brain to form small venous structures in the pia mater. These larger venous channels then form cerebral veins, which bridge the subarachnoid space and enter into endothelial-lined sinuses within the dura mater.
Venous Drainage of The Brain Learn Human Anatomy
The venous drainage of the brain does not follow the arteries of the brain. Instead, they drain to the dural sinuses, which subsequently drain to the internal jugular vein. Generally, the walls of these drainage pathways are formed by visceral periosteum and dural reflection, both lined with endothelium. The inferior sagittal and straight.

Venous Drainage of the Brain Anatomy Geeky Medics
Venous drainage of the brain occurs through a system of cerebral and cerebellar veins, which in turn drain into the dural venous sinuses. The dural venous sinuses ultimately empty into the internal jugular veins which, together with the external jugular vein (draining the scalp and face), returns venous blood from the head and neck region back.
