Ultrastuctural study on the relations among nerve elements and ependymal cells of the "Bradypus tridactylus".
On hand of the electonmicroscope, the authors study 24 parts of the encephalic ventricles in samples of Bradypus tridactylus, relating the nervous structures to the ependymal lining, chiefly emphasizing the presence of intraventricular unmyelinated fibres. In various of these regions, typical nerve fibres and other intraventricular cell projections, that cannot be taken as nerve structures, because of the continuity they show along with ependymal cells, were observed. Finally they make an analysis of some functions related to arrangements of this nature.
