Abstract:
By the routine electron microscopy the ultrastructure of the epididymis of 10 rats is studied.Except the principal cells,there is no significant difference in the ultrastructure of the other cell types of the epididymal epithelium between segments.The principal cell shows the ultrastructural characteristics of secretion and absorption.However,the ultrastructural characteristics of the principal cells in the proximal epididymvs show more tendency to absorbent and that in the distal epididymis show more tendency to secretory.Further-more it is observed that some halo cells are surrounded by small cells which possess long processes.Some or a few number of clear cells in the caudal epididymis contain some crystaloid inclusions in their basal cytoplasm.The presence of the fenestrated capillary in the peritubular tissue is also found.The meaning of the ultrastructures mentioned above is discussed.
