In the present study two types of sweat glands were observed i.e., apocrine and merocrine. The free surface of the cells in apocrine sweat glands had cytoplasmic protrusion indicating secretory activity and the merocrine sweat glands were made of tubules of cuboidal or flattened cells.
The mechanism of mucus secretion remains unclear, and the secretory granules in the chief cell of the gallbladder epithelium were microscopically observed to secrete mucus by a mechanism similar to that of merocrine secretion [9].
Apocrine glands also use merocrine or exocytosis of vesicles
