Ependymogenesis of the Lizard Basal Areas1. Ependymal Zones

Abstract

A study of the ependymary covering at (OM and EM) all levels of all ependymal zones of the Basal Areas of the Telencephalon has been caried out [vz(b), vz(e) and vz(f)], during the embryonic, postnatal and adult development of Gallotia galloti. The telencephalic vesicle is iniciated at E-30, its ventricular wall is covered by a thick hoogenous matrix (dorsal and ventral) that gradually differentiates through embryonic development in the mentioned ependymal zones and in four sulcus (sulcus lateralis, terminalis, ventralis and septomedialis) and the adult will give to the lateral ventricle a regionalized aspect, denominated as mosaic.
