The ventricular system is a set of four interconnected cavities in the brain, where the cerebrospinal fluid is produced. Within each ventricle is a region of choroid plexus, a network of ependymal cells involved in the production of CSF. The ventricular system is continuous with the central canal of the spinal cord allowing for the flow of CSF to circulate. All of the ventricular system and the central canal of the spinal cord are lined with ependyma, a specialised form of epithelium.
This ventricle has a roof and a floor. The roof is composed of the cerebellum, located at the back of the brain, and the floor is formed by the rhomboid fossa, a depression in the brainstem. Within the floor is the facial colliculus, sulcus limitans, and the obex. Much like other portions of the ventricular system inside the brain, the fourth ventricle develops from the area inside the neural tube (the structure in an embryo that becomes the brain and spinal cord) called the central canal.
