Salivary Glands | histology - University of Michigan
Compare the appearance of mucous and serous secretory cells and be sure you can tell the difference. The secretory cells are organized into secretory units or acini, and they are classified according to the cell types they contain: serous acini - contain only serous cells and are generally spherical; mucous acini - contain only mucous cells and ...

2017年7月21日 · Serous: The serous secretions are involved in solubilizing dry food, maintaining oral hygiene, and initiating starch digestion. Mucous: The mucous secretions are involved in lubricating the oral cavity and making food into the slippery bolus.
Oral: The Histology Guide - University of Leeds
Salivary glands are made up of secretory acini (acini - means a rounded secretory unit) and ducts. There are two types of secretions - serous and mucous. The acini can either be serous, mucous, or a mixture of serous and mucous. A serous acinus secretes proteins in an isotonic watery fluid.
Serous and mucous acini of the submandibular gland (100 X ...
2014年5月26日 · The submandibular gland is classified morphologically as a tubuloacinar gland. It is a mixed gland composed predominantly of serous acini. These acini stain darker than the mucous acini and is what makes up the bulk of the gland, as you can see in the image.
Parotid Gland - WebPathology
Higher magnification shows several serous acini and striated ducts. The serous acini consists of round or oval shaped clusters of epithelial cells surrounded by a basement membrane. The epithelial cells have a basally located nucleus and moderate amount of cytoplasm with basophilic zymogen granules.

Serous acini secrete a protein-rich product containing various digestive enzymes. These secretory products stain well with eosin, giving the apical cytoplasm where these secretory vesicles are stored an intense pink color.

2022年5月12日 · An acinus (from Latin, grape; plural, acini) is a small ball of secretory epithelial cells containing a tiny central lumen. Acini are usually formed by serous cells. [Acini are sometimes called alveoli, from L., small cavity.] A typical acinar cell is shaped like a pyramid.
Pancreas histology: Exocrine & endocrine parts, function - Kenhub
2023年10月30日 · The exocrine component of the pancreas makes up about 98% of the pancreatic tissue. It is comprised of densely packed serous acinar (tubuloacinar) glands. These glands are called pancreatic acini, which represent the secretory units of the pancreas. They are formed out of simple epithelium.
Accessory digestive organs: Histology - Kenhub
2023年10月30日 · The acini can either be serous, mucous, or a mixture of serous and mucous: a serous acinus secretes proteins in an isotonic watery fluid (spherical shape). a mucous acinus secretes mucin – a lubricant (tubular shape).
Anatomy, Head and Neck, Salivary Glands - StatPearls - NCBI Bookshelf
2023年5月29日 · There are three main types of acini: serous, mucinous, and seromucous. Serous acini are relatively spherical and produce a watery secretion containing proteins modified and stored in secretory or zymogen granules, abundant at the cell's apex.
