Cerebral veins are blood vessels located in the brain that are responsible for draining deoxygenated blood away from the brain tissue. They collect blood from the brain's capillaries and transport it to larger veins, eventually leading to the internal jugular vein and the heart. These veins are categorized into superficial and deep veins, depending on their location. Superficial veins are found on the surface of the brain, while deep veins are located within the brain's substance. Proper functioning of cerebral veins is crucial for maintaining healthy brain circulation and preventing conditions like stroke or venous sinus thrombosis.
