Summary
The ultrastructure of monkey eccrine sweat glands is described. The secretory portion of the sweat gland is discussed in detail. The morphological differences in the secretory coil using three different fixatives and fixative combinations are emphasized. The secretory product of dark cells is seen to have three distinct appearances depending upon the fixative used. The biochemical significance of the latter finding is discussed. The appearance of clear cell cytoplasmic processes is described using the different fixatives. The similarity of adjacent clear cell processes to those of avian salt glands is pointed out and discussed. Evidence is presented to indicate that dark cells arise from clear cells via an intermediate cell type. The appearance of the clear cell plasma membrane is described and the necessity for the use of the general term “multilaminar plasma membrane” is discussed.
