context_page_description: The ventricular system is a set of four interconnected cavities known as ventricles in the brain. Within each ventricle is a region of choroid plexus which produces the circulating cerebrospinal fluid. The ventricular system is continuous with the central canal of the spinal cord from the fourth ventricle, 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 connected by tight junctions that make up the blood–cerebrospinal fluid barrier.
