Description
Abstract
The morphological features of the
ependymal surface and supraependymal elements of
the fourth ventricle of the rat were examined by
scanning electron microscopy (SEM) and by the
transmission electron rnicroscopy (TEM). The results
confirm the following aspects: 1) The presence of
supraependymal elements and microvilli in the
ependymal territories, including the sites where the
cilia completely cover the ependymal surface; 2) The
existence of cilia with oval or sphencal thickenings
together with supraependymal bulbs similar in size to
those of the larger ciliary swellings; 3) Identification
of the long supraependymal fibres with intermittent
fusiform dilations observed under the SEM with the
neme fibres seen under the TEM; 4) The existence of
intraventricular axodendritic synapses.
