title: Ultrastructural study of the cellular components of the organum vasculosum lamina terminalis of the rabbit (Oryctolagus cuniculus).
abstract: We studied the organum vasculosum of the lamina terminalis (OVLT), under the electron microscope (transmission and scanning) to determine its ultrastructural features. Two cell types are differentiated. Type I cells are typical ependymal cells bearing few cilia. Type II cells present a tanycytic morphology. The latter present a long basal process which travels from the perikarya and intermingles with other neuronal components, finally reaching the perivascular spaces where it comes into close contact with fenestrated capillaries.
