The brain ventricles are cavities in the brain that hold cerebrospinal fluid (CSF). There are 4 ventricles. Two lateral ventricles, one third ventricle and one fourth ventricle.

There are four ventricles in the interior of the brain, chambers filled with cerebrospinal fluid which is produced there. Once formed the CSF circulates through the ventricles and into the subarachnoid space bathing and floating the brain.
