Flax Cerebri * The separations of the two layers of the dura mater create the dural venous sinuses. The venous sinuses receive the blood from the veins draining the brain, and this blood flows from the venous sinuses to the internal jugular veins. The walls of the sinuses are line by endothelium. * The brain has four internal chambers called ventricles * lateral ventricles- two lateral ventricles, one in each cerebral hemisphere * third ventricles- beneath the corpus callosum and surrounded by the thalamus. * fourth ventricle- between the hemispheres of the cerebellum. Ventricles * interventricular foramen (Foramen of Monro)- tiny passage that connects lateral ventricles to the third ventricle * cerebral aqueduct (aqueduct of Sylvius ) - small canal that passes down the core of the midbrain and leads to the fourth ventricle (a small chamber between the pons and cerebellum * central canal- extension of the fourth ventricle through the medulla oblongata into the spinal cord.
