Cavities within the brain containing cerebrospinal fluid are called ventricles. The brain consists of four primary ventricles: two lateral ventricles, the third ventricle, and the fourth ventricle. These structures are crucial for the production, circulation, and absorption of cerebrospinal fluid (CSF), which serves to protect the brain, provide buoyancy, and remove waste. The CSF flows through the ventricles and around the brain and spinal cord, playing an essential role in maintaining a stable environment for neural function. In addition to their protective function, ventricles also help to nourish the brain by delivering nutrients and removing toxins.
