Overall Morphology of Basement Membrane of Rat Seminiferous Tubule as Revealed by Scanning Electron Microscopy

Scanning electron microscopic observation of the basal surface of the basement membrane of the rat seminiferous tubule has revealed that the basement membrane appears to be like a tiled floor, and formation of meshwork structure of collagen fibrils is evident in some exfoliated areas of basement membrane. This meshwork structure is considered to ensure fluid regulation from the intertubular medium toward the lumen of the seminiferous tubules.
