Merocrine

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 then onto a bodily surface or into the lumen.

Exocrine secretion
Merocrine or eccrine – by exocytosis
Apocrine – by membrane budding (loss of cytoplasm)
Holocrine – by membrane rupture
Merocrine secretion

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
gollark: I guess I could procgen borders and box shadows and such.
gollark: How would you suggest I alter it exactly? It probably wouldn't make much sense to arbitrarily split the experiments into differently formatted bits.
gollark: But really, you can read alphabetically and it works.
gollark: I suppose it's possible that most users aren't exposed to the colours enough that they learn to associate them with anything usefully.
gollark: 2021ish?
