title: Scanning electron microscopy of the wall of the third ventricle of the brain of Rana temporaria. III. Electron microscopy of the ventricular surface of the median eminence.
abstract: From combined scanning and transmission electron microscopic studies it is concluded (1) that all surface specializations of the median eminence of Rana temporaria are protrusions of ependymal cells; (2) that the microvillus-like structures of the median eminence are transient differentiations of the ependymal cell surface, associated with the activity of the ependymal cells.
