Histologic Variations in the Structure of Human Eccrine Sweat Glands

The Ultrastructure and Histophysiology of Human Eccrine Sweat Glands

The electron microscopy of human eccrine sweat glands has been studied before and after stimulation by pilocarpine iontophoresis. The identity of the dark and clear cells in the secretory segment as defined by Montagna et al. (23) was determined by studying serial sections, thin for electron microscopy and thick for light microscopy. Cells with numerous apical secretory vacuoles are termed muco...

Metabolic studies of isolated human eccrine sweat glands.

This paper describes a method for isolating and studying the metabolism of human eccrine sweat glands. (a) Electron microscopy of glands which had been isolated and then incubated for an hour revealed no apparent alteration in morphology. (b) Known variation in gland size (male > female > children) was reflected in the relative rates of lactate production. (c) Lactate production was approximate...

Secretion of eccrine sweat glands during exercise.

Electron microscopic study on human eccrine sweat glands.

Electron microscope observations on eccrine sweat glands have been carried out by many workers, namely on human eccrine swear glands by HIBBS (1958), IIJIMA (1959), CHRALES (1960), KUROSUMI et al. (1960), and MUNGER (1961) and on those of animals by KITAMURA (1958), MUNGER et al. (1961), ELLIS et al. (1961), MATSUZAWA et al. (1963), KUROSUMI et al. (1964) and TERZAKIS (1964). Already by means o...

Fine Structure of the Myoepithelium of the Eccrine Sweat Glands of Man

The secretory coils of glutaraldehyde-osmium tetroxide-fixed and Epon-Araldite-embedded eccrine sweat glands from the palms of young men were studied with the electron microscope. The myoepithelial cells lie on the epithelial side of the basement membrane and abut other epithelial elements directly. The irregularly serrated base of the cell has dense thickenings along the plasma membrane which ...
