2022年6月11日 · The pancreas is a compound, acinar, serous, exocrine gland with islets of endocrine cells. One single acinus, composed of several serous cells, is outlined in the center of the image. The dashed outline follows the basement membrane of the acinus, upon which the base of each secretory epithelial cell rests.

The Acinus The exocrine pancreas is classified as a compound tubuloacinous gland. The cells that synthesize and secrete digestive enzymes are arranged in grape-like clusters called acini , very similar to what is seen in salivary glands.

2023年10月30日 · These glands are called pancreatic acini, which represent the secretory units of the pancreas. They are formed out of simple epithelium. Each pancreatic acinus consists of pyramidal-shaped acinar cells, which have a broad basal portion and a narrow apical surface that surround a small central lumen.

2018年1月1日 · The fundamental secretory unit of the exocrine pancreas is the acinus, a collection ~ 20–200 acinar cells, adjacent centroacinar cells which protrude into the lumen of the acinus, and proximal small ducts (Fig. 39.2). The collective function of the cells in the acinus is to combine exocytosed secretory proteins from individual acini with ...

The pancreatic acinar cell is the functional unit of the exocrine pancreas. It synthesizes, stores, and secretes digestive enzymes. Under normal physiological conditions, digestive enzymes are activated only once they have reached the duodenum. Premature activation of these enzymes within pancreatic …

The pancreas is a glandular organ in the digestive system and endocrine system of vertebrates. It is both an endocrine gland that produces several important hormones—including insulin, glucagon, somatostatin, and pancreatic polypeptide—as well as a digestive organ that secretes pancreatic juice that contain digestive enzymes to assist the ...

Discuss the cellular structure of an exocrine pancreatic acinus and its function and products. Identify intercalated ducts and centroacinar cells and know their functions. Recognize islets of Langerhans (endocrine pancreas).

2006年1月1日 · The pancreatic acinar cell is the functional unit of the exocrine pancreas. It synthesizes, stores, and secretes digestive enzymes. Under normal physiological conditions, digestive enzymes are activated only once they have reached the duodenum.

The morphology of the exocrine secretory unit of the pancreas, i.e. the pancreatic acinus, is reviewed. The histological features of the acini and their relation with the duct system are described. The acinar three-dimensional architecture was studied by means of different ultrastructural techniques …

2016年6月28日 · The acinus is the functional unit of the exocrine pancreas, which is composed of contiguous pyramid-shaped glandular cells with their apex toward the lumen of the acinus. Acinar cells have well-developed Golgi and rough endoplasmic reticulum complexes, essential for synthesizing and storing large amounts of secretory proteins.
