Choroid Plexus In the four cerebral ventricles, the ependymal layer is modified to perform a secretory function and forms the choroid plexus. In development, the innermost meningeal layer, the pia mater, in these areas becomes highly vascularized and projects into the ventricle as a series of villus-like processes called the choroid plexus (arrow). Cerebral cortex flanks the choroid plexus, and part of the cerebellum (arrowhead) is above the villi. (c) 1998 Keyboard Publishing, Inc.
