Interventricular Foramen
Interventricular Foramen
A small opening that connects the lateral ventricles to the third ventricle, allowing the flow of cerebrospinal fluid.
Role of cerebrospinal fluid
Role of cerebrospinal fluid
It cushions and protects the brain and spinal cord, removes waste products, and helps regulate the intracranial pressure.
CSF exit from fourth ventricle
CSF exit from fourth ventricle
The fourth ventricle has openings that allow cerebrospinal fluid to flow out into the subarachnoid space, surrounding the brain and spinal cord.

Study Notes
Cerebrospinal Fluid (CSF)
- CSF passes from the lateral ventricles to the third ventricle through the interventricular foramen (foramen of Monro).
- CSF plays a crucial role in the body, regulating the extracellular environment of neurons along with the blood-brain barrier.
CSF Formation and Circulation
- The major quantity of CSF is formed in the choroid plexus of the lateral ventricles.
- CSF exits the fourth ventricle through the median aperture (foramen of Magendie) and the lateral apertures (foramina of Luschka).
- CSF passes from the fourth ventricle to the subarachnoid space through the median aperture (foramen of Magendie) and the lateral apertures (foramina of Luschka).
- After circulating through the subarachnoid space over the spinal cord and cerebral hemispheres, CSF flows into the dural venous sinuses.
