what veins drain blood into the confluence of sinuses?
Consequently, an efficient system had to be established in order to allow blood to leave the restricted compartment. 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.
