An acinus (//) (plural, acini; adjective, acinar [//] or acinous) refers to any cluster of cells that resembles a many-lobed berry, such as a raspberry (acinus is Latin for "berry"). The berry-shaped termination of an exocrine gland, where the secretion is produced, is acinar in form, as is the alveolar sac containing multiple alveoli in the lungs.

Exocrine glands[edit]
Acinar exocrine glands are found in many organs, including:
- the stomach[1]
- the sebaceous gland of the scalp
- the salivary glands of the tongue[2]
- the liver
- the lacrimal glands
- the mammary glands
- the pancreas [3]
- the bulbourethral (Cowper's) glands
The thyroid follicles can also be considered of acinar formation but in this case the follicles, being part of an endocrine gland, act as a hormonal deposit rather than to facilitate secretion.
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.
Lungs[edit]
The respiratory bronchioles in the lungs terminate in acini, many-lobed sacs containing groupings of alveoli.
