It surrounds and protect the brain and the spinal chord
Meninges

Dura mater
Where do the folds of the dura mater extend into the longitudinal fissure?
Between the two cerebral hemispheres and between the cerebrum and the cerebellum
It collects blood from the small veins of the brain
Dural venous sinuses
Where does the blood collected by the dural venous sinuses empty into?
Empty into the internal jugular veins
It is the space between the dura mater and the arachnoid mater
subdural space
What is between the arachnoid mater and the pia mater
subarachnoid space
The CNS contains fluid-filled cavities, called
ventricles
Each cerebral hemisphere contains a relatively large cavity called the
The lateral ventricle
It is a smaller, midline cavity located in the center of the diencephalon between the two halves of the thalamus and connected by foramina to the lateral ventricles
The third ventricle
It is located at the base of the cerebellum and connected to the third ventricle by a narrow canal called cerebral aqueduct
The fourth ventricle
The fourth ventricle is continuous with the _________ of the spinal cord
central canal
it is a clear, colorless, watery fluid that flows in and around your brain and spinal cord.
Cerebrospinal fluid
It bathes the brain and spinal cord, providing a protective cushion around the CNS
