Fig. 31
High-power electron micrograph of the apical region of a ciliated cell presenting basal bodies (B), cilia (c), a few small coated and uncoated pits (arrowheads), apical tubules (T), numerous subsurface vesicular profiles, pale multivesicular bodies (MVB), glycogen granules (circled), and filaments (f)

Diagrammatic representation of a principal epithelial cell from the initial segment of the epididymis
Fig. 34
Apical region of a principal cell from the initial segment of the epididymis showing large coated and uncoated pits of the cell surface (large arrowheads), numerous cisternae of the sparsely granulated endoplasmic reticulum (ER), several large smooth-surfaced vesicles showing a patchy flocculent material (asterisks) and the occasional small coated and uncoated vesicles (small arrowheads)
Fig. 35
High-power electron micrograph of the apical region of a principal cell from the initial segment of the epididymis. Numerous cisternae of the sparsely granulated endoplasmic reticulum (ER) containing a unifom filamentous material are evident, some of which can be seen in close proximity to the apical plasma membrane (arrows)
