SCANNING ELECTRON MICROSCOPIC STUDY OF AMNION IN THE MICROCHIROPTERAN BAT, HIPPOSIDEROS SPEORIS AND HUMAN AT FULL TERM PREGNANCY

Abstract

On Scanning Electron Microscopy, at low magnification the single layered amniotic surface appeared to be
thrown into folds in (Microcheropteran bat, Hipposideros Speoris Schneider) in near term and polygonal cell
gave a mosaic or “cobblestone”appearance was due tot he presence of deep recesses or troughs between
adjacent cells. In the intracellular gap openings or “ostia” were common. In human being on SEM four
patterns were observed two were the pattern were surrounded by intracellular channels and in other large flat
cells observed. The Microvilli in all four pattern, variable morphology in different samples observed. Possible
functional implications of the findings are discussed.
