this is the name of the fluid that fills the brain ventricles

cerebralspinalfluid

specific cells that generate cerebrospinal fluid

ependymal cells

leaky blood vessels in the brain that provides the fluid for CSF

chlorid plexus

2 ventricles found in the cerebral hemisphere

lateral ventricles

ventricle found in the diencephalon (inside the thalamus)

3rd ventricle

ventricle found in the brainstem, anterior to cerebellum

4th ventricle

tubes that move CSF from the lateral ventricles to the 3rd ventricle

intraventricular foramen

tube that moves CSF from the 3rd ventricle to the 4th ventricle

cerebral aqueduct

tube that drains CSF from the 4th ventricle into the spinal cord

central canal

CSF-filled space between the pia mater and arachnoid mater

subarachnoid space

small openings in the arachnoid mater that allows CSF to drain into the dural venous sinus

arachnoid villi

blood filled space where the extra CSF returns to the bloodstream
