Saliva is a mixture of fluids secreted by large and small salivary glands. Plasma membrane events during secretion of the parotid and submandibular glands of humans and rats were observed in living cells by confocal microscopy and from the cytoplasmic side by scanning electron microscopy after removal of the cell organelles by the OsO4 maceration method. These new microscopic techniques revealed in acinar cells two distinct exocytosis-endocytosis coupling mechanisms elicited in response to different secretory stimuli.
