Question

Which part of the brain does not have its own source of ventricle?

Answer 1

The cerebral cortex is the part of the brain that does not have its own source of ventricles. The ventricles are a network of interconnected, fluid-filled spaces within the brain that help to cushion and protect the brain from injury. There are four ventricles in the brain: the two lateral ventricles, the third ventricle, and the fourth ventricle.
While the cerebral cortex is a highly convoluted and folded outer layer of the brain that plays an important role in perception, consciousness, and voluntary movement, it does not contain any ventricles of its own. Instead, the ventricles are located deeper within the brain, surrounded by other structures such as the thalamus, hypothalamus, and brainstem. The cerebral cortex is supplied with cerebrospinal fluid (CSF) that is produced in the ventricles and flows around and through the brain and spinal cord, helping to provide nutrients and remove waste products.
