Fig. 16
Portion of the epithelium (E) lining the distal segment of the vas deferens
Fig. 17
Tall columnar principal (P) epithelial cells lining the distal segment of the vas deferens showing a brush border (asterisk) and moderately stained nucleus (n) usually in the midregion of the cell
Fig. 18
A diagrammatic representation of a nonciliated cell from the terminal zone of the ductuli efferentes
Fig. 19
Apical and supranuclear regions of a nonciliated cell from the initial zone of the efferent ducts
Fig. 20
Apical and supranuclear regions of a nonciliated cell from the terminal zone of the efferent ducts
Fig. 21
High-power electron micrograph of the apical region of a nonciliated cell. Tubular coated pits (cp) connected to the apical plasma membrane can be seen extending into the cell cytoplasm from the bases of the microvilli (Mv)
Fig. 22
High-power electron micrograph of the apical region of a nonciliated cell. Tubular coated pits (cp) presumed to be still connected to the cell surface are evident
Fig. 23
High power of the apical region showing numerous apical tubules (T) with a uniform, moderately dense staining content, some of which can be seen to be connected (arrowheads) to large dilated spherical membranous bodies (asterisks), showing an empty, pale stained lumen lined by a fuzzy material
Fig. 24
A large vacuole, containing a fine flocculent material, referred to as an endosome (E) is seen in the apical region to which is connected an apical tubule (T, arrowhead)
Fig. 25
Junction between the apical and supranuclear regions of a nonciliated cell of the terminal zone
Fig. 26
Supranuclear region of a nonciliated cell showing several homogeneous dense lysosomes (L)
Fig. 27
A membrane-bound body deep in the supranuclear region of a nonciliated cell showing features of a dense lysosome (L) and lipid (LIP) delimited by a common unit membrane
Fig. 28
A membrane-bound body next to the nucleus (N) of a nonciliated cell showing features of a dense lysosome (L) and lipid (LIP)
Fig. 29
A well-defined tubular network of a nonciliated cell formed of short anastomosing tubes demarcating pores of various sizes (asterisks) is seen to be connected at several sites (small arrowheads) with the lateral plasma membrane (PM)
Fig. 30
Low-power electron micrograph showing tall columnar ciliated cells (C) and adjacent nonciliated cells (NC)
