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).

Define Holocrine

Holocrine is a term used to classify the mode of secretion in exocrine glands in the study of histology. Holocrine secretions are produced in the cytoplasm of the cell and released by the rupture of the plasma membrane, which destroys the cell and results in the secretion of the product into the lumen.

(Hint: Think Holocaust, the cell is destroyed)

Apocrine is a term used to classify exocrine glands in the study of histology. Cells which are classified as apocrine bud their secretions off through the plasma membrane producing membrane-bound vesicles in the lumen. This method is also calleddecapitation secretion. The apical portion of the secretory cell of the gland pinches off and enters the lumen.

Apocrine secretion is less damaging to the gland than holocrine secretion (which destroys a cell) but more damaging than merocrinesecretion (exocytosis).

An example of true apocrine glands are mammary glands, responsible for secreting breast milk.^[1]

 (Hint: Think Apart. The secretion buds and the breaks Apart)

Eccrine Glands

Sweat Glands That Produce Oily, Odorless Secretes That Become Odorous Due to Bacteria. Found In Axilary Region.

Note: Modified Apocrine Glands Include Mamary Glands (Milk), Ciliary Glands (Tears), Ceruminous Glands (Earwax)
