What is the difference between serous cells and mucous cells?

What is the difference between serous cells and mucous cells?

The main difference between serous and mucous is that serous gland secretes a thin, watery secretion containing zymogens, antibodies, and inorganic ions, which are mainly involved in digestion and defense whereas mucous gland secretes a thick, viscous secretion, containing mucin, which is mainly involved in lubrication …

What is the difference between mucous secretion and serous secretion?

Mucus is a thick, clear, and somewhat slimy substance. Serous secretion is a more liquid opalescent fluid composed of water and proteins, such as the digestive enzyme amylase.

What is the difference between serous and mucous acini?

serous acini – contain only serous cells and are generally spherical. mucous acini – contain only mucous cells and are generally tubular. mixed (or sero-mucous) acini -contain a mixture of serous and mucous cells.

Why are mucous glands pale staining?

Mucous cells have a pale-staining, bubbly cytoplasm and nuclei that appear to be pushed against the basal cell membrane. In contrast, the cytoplasm of serous cells contain distinctly eosinophilic zymogen granules and their nuclei are spherical in appearance.

What is the functional difference between serous acinar cells and mucous acinar cells?

Two basic types of acinar epithelial cells exist: serous cells, which secrete a watery fluid, essentially devoid of mucus. mucous cells, which produce a very mucus-rich secretion.

What are serous cells?

serous cell. A cell, especially of the salivary gland, that secretes a watery or thin albuminous fluid, as opposed to a mucous cell.

Are minor salivary glands mucous or serous?

Minor salivary glands. Labial and buccal glands: The glands of the lips and cheeks are a mixed gland consisting of mucous tubules with serous demilunes.

What do mucous cells secrete?

Mucous cells populate the mucous glands of the cardia and antral regions and secrete mucus and pepsinogen II.

What do serous cells produce?

Which of the following salivary glands produce only a serous product?

Acini in the parotid glands are almost exclusively of the serous type, while those in the sublingual glands are predominantly mucus cells.

What cells produce mucous?

In the airways – the trachea, bronchi, and bronchioles, the lining of mucus is produced by specialized airway epithelial cells called goblet cells, and submucosal glands.

Are mucus secreting cells?

Goblet cells are specialized for the synthesis and secretion of mucus. They acquired their name for their typical goblet, cup-like, appearance formed by the mucin granulae that fill up the cytoplasm (Figure 1).
