Notes:
The rat preputial gland is a morphologically complex structure active in both lipid and protein secretion. By electron microscopy, its acinar cells contain an extensively developed endoplasmic reticulum and numerous Golgi vacuoles, where the protein secretory granules apparently arise. As the granules mature, they assume a crystalloid configuration and, after losing their surrounding membranes when the cell degenerates, are deposited in an excretory duct along with lipid and cellular debris. The granules are apparently unrelated either to mitochondria or to tonofiliments, but seem to represent a true protein secretion of the acinar cell itself.
