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== Acinar exocrine glands are found in many organs, including: * the stomach〔 - pyloric stomach〕 * the sebaceous gland of the scalp * the salivary glands of the tongue〔 - sublingual gland〕 * the liver * the lacrimal glands * the mammary glands * the pancreas * 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. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Acinus」の詳細全文を読む スポンサード リンク
