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 stomach [OklahomaHistology|51_07 - pyloric stomach]

* the sebaceous gland of the scalp

* the salivary glands of the tongue [OklahomaHistology|46_03 - sublingual gland]

* the liver

* the lacrimal glands

* the mammary glands

* the pancreas [BUHistology|10405loa]

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.

ee also

* Intercalated duct
