What is the function of serous Acinus?

A serous acinus secretes proteins in an isotonic watery fluid. In a mixed serous-mucous acinus, the serous acinus forms a serous demilune around mucous acinus, as shown in the diagram.

What is the function of serous cells?

serous cells, which secrete a watery fluid, essentially devoid of mucus. mucous cells, which produce a very mucus-rich secretion.

Which of the following glands has serous Demilunes?

The sublingual gland also is a mixed gland, but mucous secretory cells predominate (Figure 11-36). The mucous tubules and serous demilunes resemble those of the submandibular gland.

What is serous secretion?

Serous secretion is a more liquid opalescent fluid composed of water and proteins, such as the digestive enzyme amylase.

What is the function of parotid gland?

The parotid gland and the other salivary glands play an essential function in the oral cavity because they secret saliva, facilitating chewing, swallowing, speaking, and digesting [2].

Where can serous Acinus be found?

Serous glands are most common in the parotid gland and lacrimal gland but are also present in the submandibular gland and, to a far lesser extent, the sublingual gland.

What are the serous cells?

An epithelial cell that secretes a watery fluid containing proteins, glycoproteins, and often antibodies (IgA, IgG, and IgM). Serous cells and mucous cells are the two varieties of secretory cells found in exocrine glands.

What do you mean by serous?

: of, relating to, producing, or resembling serum especially : having a thin watery constitution a serous exudate.

Which gland is purely serous?

Parotid glands
5.1. Parotid glands: The parotid gland is a purely serous gland, and all the acinar cells are similar in structure to the serous cells (Figures 2 and 3).

What is the function of the serous demilune cell?

These demilune cells secrete the proteins that contain the enzyme lysozyme, which degrades the cell walls of bacteria. In this way, lysozyme confers antimicrobial activity to mucus. The serous demilune is an artifact from traditional methods of preparing samples.

How is lysozyme used to preserve serous demilune?

Serous demilune. In this way, lysozyme confers antimicrobial activity to mucus. The serous demilune is an artifact from traditional methods of preparing samples. Samples are traditionally preserved and fixed in formaldehyde. When samples were preserved by quick-freezing in liquid nitrogen and then fixed with osmium tetraoxide in acetone,…

What are the serous demilunes of the salivary glands?

Serous demilunes are the serous cells at the distal end of mucous tubuloalveolar secretory unit of certain salivary glands. These demilune cells secrete the proteins that contain the enzyme lysozyme, which degrades the cell walls of bacteria. In this way, lysozyme confers antimicrobial activity to mucus. The serous demilune is an…

Which is part of the salivary gland secretes lysozyme?

Serous demilune. Serous demilunes are the serous cells at the distal end of mucous tubuloalveolar secretory unit of certain salivary glands. These demilune cells secrete the proteins that contain the enzyme lysozyme, which degrades the cell walls of bacteria. In this way, lysozyme confers antimicrobial activity to mucus.
