Ventricle of the Brain Fourth

The fourth ventricle of the brain (ventriculus quartus, pna, bna, jna) is one of the cavities of the brain. Located in the posterior cranial fossa, between the cerebellum and medulla oblongata. It communicates with the third and lateral ventricles through the cerebral aqueduct (aqueductus cerebri).

The fourth ventricle of the brain is lined with ependyma and filled with cerebrospinal fluid. Plays an important role in the circulation and drainage of cerebrospinal fluid, as well as in the regulation of intracranial pressure.

The walls of the fourth ventricle are formed by the cerebellum at the back and the medulla oblongata at the front. At the bottom of the ventricle there is a rhomboid fossa (fossa rhomboidea).

Pathological changes in the fourth ventricle, such as tumors or cysts, can lead to disturbances in CSF flow and intracranial hypertension. Therefore, visualization of the fourth ventricle has important diagnostic value.

The ventricles of the brain are cavities that are filled with cerebrospinal fluid (CSF); they are located in the substance of the brain. The ventricular system of the brain includes four ventricles - the hindbrain (III ventricle) and the cerebrum (IV ventricle).

The fourth ventricle is a common part of all parts of the brain and includes large gray and white matter. It separates the cerebral hemispheres and
