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.
