|Merocrine or eccrine – by exocytosis|
|Apocrine – by membrane budding (loss of cytoplasm)|

Merocrine(or eccrine) is a term used to classify exocrine glands and their secretions in the study of histology. A cell is classified as merocrine if the secretions of that cell are excreted via exocytosis from secretory cells into an epithelial-walled duct or ducts and thence onto a bodily surface or into the lumen.
