The fine structure of the ependymal surface of the recessus infundibularis in the rat






Anatomy and Embryology 151(3): 241-266

The fine structure of the ependymal surface of the recessus infundibularis in the rat

The surface of the recessus infundibularis of the 3rd ventricle has been studied with the scanning and transmission technique in normal and experimental material. Surface specializations such as microvilli, craters and areas of discontinuous lining are described. Supraependymal cells and fibers have been found; some of these cells form wide-meshed networks. The supraependymal fibers may be regular or varicose; the former seem to perforate the ependyma. With the transmission electron microscope the supraependymal cells are divided into 3 categories: nerve cells, lymphocytes and dense cells. Two fiber populations are distinguished: thin profiles (nerve fibers) and thick profiles (nerve terminals). Axosomatic and axoaxonic synapses are described. Synapses between supraependymal fibers and ependyma cells also are found.
