An acinus (/ ˈ æ s ɪ n ə s /; pl.: acini; adjective, acinar / ˈ æ s ɪ n ər / or acinous) refers to any cluster of cells that resembles a many-lobed "berry", such as a raspberry (acinus is Latin for "berry").

The meaning of ACINUS is any of the small sacs terminating the ducts of some exocrine glands and lined with secretory cells.

The acinus is a functional unit mainly dedicated to the production and secretion of digestive enzymes (6 as much as 20 g daily). It is composed of 15 to 100 pyramidal-shaped cells (as much as 30 µm apical base height) known as acinar cells (Cleveland et al, 2012).

The structure of the human pulmonary acinus has been described infrequently. The aim of the study was to determine the branching pattern of respiratory bronchioles and alveolar ducts in a human acinus from the peripheral part of the lung, where ...

One of the minute grape-shaped secretory portions of an acinous gland. Some authorities use the terms acinus and alveolus interchangeably, whereas others differentiate them by the constricted openings of the acinus into the excretory duct.

The hepatic acinus is the functional unit of the liver. The acinus is more difficult to visualize than the lobule, but represents a unit that is of more relevance to hepatic function because it is oriented around the afferent vascular system.

An acinus is a small, grape-like cluster of cells that forms part of a gland, particularly in the pancreas and salivary glands. These structures are responsible for the production and secretion of digestive enzymes and saliva, playing a vital role in the digestive process.

Development of the acinus in the human lung. Development and remodelling of the acinus (those structures distal to the terminal bronchiolus) occurs during fetal life and childhood.

In the walls of the acini are pyramidal secreting cells and some flat, star-shaped contractile cells called myoepithelial, or basket, cells. The latter… …the duodenum, are composed of acini (round sacs) and tubules that are twisting and have multiple branching. These glands empty into the base of Lieberkühn’s glands in the duodenum.
