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: -The ventricles of the brain are a communicating network of cavities filled with cerebrospinal fluid (CSF) and located within the brain parenchyma. The ventricular system is composed of 2 lateral ventricles, the third ventricle, the cerebral aqueduct, and the fourth ventricle (see the images below).

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.

Detailed explanation-4: -The first and second ventricles are lateral ventricles. These C-shaped structures are located on each side of your cerebral cortex, the wrinkly outer layer of your brain. The third ventricle is a narrow, funnel-shaped structure situated between your right and left thalamus, just above your brain stem.
