Merocrine or eccrine – by exocytosis

Apocrine – by membrane budding (decapitation secretion)

Holocrine – by membrane rupture

Merocrine 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.

Merocrine is the most common manner of secretion. The gland releases its product and no part of the gland is lost or damaged (compare holocrine and apocrine).

The term eccrine is specifically used to designate merocrine secretions from sweat glands (eccrine sweat glands).^[1]

Examples

• Salivary glands
• Pancreatic glands
• Certain sweat glands ( eccrine and apocrine)
