The fourth ventricle is a cavity located in the brainstem, specifically between the brainstem and the cerebellum. Its primary functions include the circulation of cerebrospinal fluid (CSF), which helps to cushion the brain and maintain intracranial pressure, as well as housing important nuclei involved in autonomic functions. Additionally, it serves as a pathway for CSF to flow into the subarachnoid space surrounding the brain and spinal cord.

The cerebrospinal fluid in the third ventricle will drain into the fourth ventricle.
if the fourth ventricle is blocked it will result in accumulation of CSF and there is no drainage of CSF into the sub -arachnoid space.
The fourth ventricle of the brain lies between the cerebellum and the brain stem. This i next to the third ventricle, which divides the left and right halves of the thalamus.
The cerebral aqueduct is the narrow conduit, between the third and the fourth ventricles in the midbrain, that conveys the cerebrospinal fluid and thereby prevents its potentially deadly buildup in the brain. Also called the aqueduct of Sylvius.
It is very important to assess the function of the left ventricle. Using a sonogram, it is often easy to tell if there is hyperdynamic function in the left ventricle which often leads to heart failure.
