Ventricles and cerebrospinal fluid
VENTRICLES AND CEREBROSPINAL FLUID ANATOMYCerebrospinal fluid can be found in the subarachnoid space, the central canal, and the ventricles. Cerebraospinal fluid is created by the active transport of particular substances in blood plasma within the choroid plexus.
The fluid itself is clear, almost like lymph fluid, and one of its responsibilities is to create a protective cushioning around and for the structures of the central nervous system. The brain rests in cerebrospinal fluid like a buoy.
The path of the cerebrospinal fluid follows the entire structure of the central nervous system and then returns to the circulatory system as a waste product by draining through the walls of the arachnoid villi, a special set of venous capillaries.
