Acini
Introduction
An acinus (adjective: acinar, plural acini) refers to the berry-shaped termination of an exocrine gland, where the secretion is produced.
They are found in many organs, including:
- the sebaceous gland of the scalp
- the salivary glands of the tongue[2]
- the liver
- the lacrimal glands
Mucous acini usually stain pale, while serous acini usually stain dark.
The term “acinus” is considered synonymous with alveolus by some sources, but not all.
