Detailed explanation-1: -The cerebral ventricular system is made up of 4 ventricles that include 2 lateral ventricles (1 in each cerebral hemisphere), the third ventricle in the diencephalon, and the fourth ventricle in the hindbrain. Inferiorly, it is continuous with the central canal of the spinal cord.
Detailed explanation-2: -Answer and Explanation: D) Initiation of nerve impulses is not a function of the CSF.
Detailed explanation-3: -Your brain floats in a bath of cerebrospinal fluid. This fluid also fills large open structures, called ventricles, which lie deep inside your brain. The fluid-filled ventricles help keep the brain buoyant and cushioned.
Detailed explanation-4: -Cerebrospinal fluid CSF is a clear, watery fluid that fills the ventricles of the brain and the subarachnoid space around the brain and spinal cord. CSF is primarily produced by the choroid plexus of the ventricles (≤70% of the volume); most of it is formed by the choroid plexus of the lateral ventricles.
