Abstract: | Summary Examination of the parotid gland of the rat has shown specific associations of cisterns of the endoplasmic reticulum with gap junctions. About 20% of the junctions are so intimately associated with cisterns of the endoplasmic reticulum that in freeze fractured material the cisternal membranes remain attached to the junctional membrane faces, obscuring most of the junctional array except for a thin ring of telltale particles. This association was seen only in the parotid gland of the rat, but not that of the other species examined. |
