Cerebrospinal fluid (CSF)

 

 

Fluid found in the ventricle of the brain and the central canal of spinal cord. It is produced in the subarachnoid granulations.

Cerebrospinal fluid (CSF) is contained within the subarachnoid space.  This space also contains subarachnoid granulations which allow for the flow of CSF in a unidirectional fashion.  The CSF flows through the arachnoid granulations into the main blood stream by entering intravenous sinuses around the brain.

The subarachnoid space communicates with the ventricular system of the brain through two lateral foramina of Luschka and one median foramen of Magendie.  CSF therefore moves freely within the ventricular system, communicating with the subarachnoid space.
