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").
In histology (microscopic anatomy), the lobules of liver, or hepatic lobules, are small divisions of the liver defined at the microscopic scale. The hepatic lobule is a building block of the liver tissue, consisting of a portal triad, hepatocytes arranged in linear cords between a capillary network, and a central vein.
Exocrine glands contain a glandular portion and a duct portion, the structures of which can be used to classify the gland. [1]The duct portion may be branched (called compound) or unbranched (called simple).
Mucoserous acini (singular acinus) or mixed acini are mainly present in submandibular and sublingual glands. They are formed by mucous cells with some serous cells interspersed each other. Both cells pour their secretion directly in the lumen. Layer of mucous cells and serous demilune of serous cells superficial to mucous cells
Serous glands secrete serous fluid. [1] They contain serous acini, a grouping of serous cells that secrete serous fluid, isotonic with blood plasma, that contains enzymes such as alpha-amylase.
Each acinus is located at the terminal part of the gland connected to the ductal system, with many acini within each lobule of the gland. Each acinus consists of a single layer of cuboidal epithelial cells surrounding a lumen, a central opening where the saliva is deposited after being produced by the secretory cells.
The exocrine pancreas is one of two compartments that include digestive-acting acinar cells and duct cells.They represent an extension of the intercalated duct into each pancreatic acinus. [1] These cells are commonly known as duct cells, and secrete an aqueous bicarbonate solution under stimulation by the hormone secretin. They also secrete ...
Examination showed that the serous cells and mucosal cells were aligned in the acinus. The traditional preparation caused mucous cells to swell during fixation which results in the serous cells being popped out of their alignment. After sectioning the serous cells resembled the common demilune shape, and were so named. [2]
