Ultrastructure of the parotid gland in rabbit with special reference to its secretory granules

ABSTRACT

The parotid gland of rabbit was examined by electron microscopy. The gland is a composite one mainly of serous type and to some extent of seromucous type. There is a great variation in the secretory granules substructure. These variations suggest the visualization of a maturation process within the secretory granules. The intercalated duct cells are secretory as they contain secretory granules. Myoepithelial cells are numerous throughout the gland and tend to encircle the intercalated ducts
