Chapter 7 describes the coverings of the brain and the ventricular system. The central nervous system (CNS) is wrapped in three membranes of connective tissue-the meninges-with fluid-filled spaces between them. The innermost membrane-pia-is thin and adheres to the surface of the brain at all places. The outermost membrane-dura-is thick and fibrous and covers the inside of the skull and spinal canal. The arachnoid is a thin membrane attached to the inside of the dura. The subarachnoid space is with cerebrospinal fluid (CSF) and lies between the pia and the arachnoid. The ventricular system consists of irregularly shaped, fluid-filled cavities inside the CNS. There are four dilatations or ventricles. Vascular choroid plexuses in the ventricles produce the CSF. Drainage of CSF occurs through arachnoid villi.
