Mucous glands, also known as muciparous glands, are found in several different parts of the body, and they typically stain lighter than serous glands during standard histological preparation. Most are multicellular, but goblet cells are single-celled glands.

The Weber's glands are muciparous glands on the side of the tongue. They are a minor salivary gland in the peritonsillar space. The glands are named after German anatomist Moritz Ignaz Weber. [1] They clear the peritonsillar space of debris. [citation needed]
MUC5B is a polymeric protein secreted from submucosal glands and some goblet cells, and this is in the form of strands. [9] [10] 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.
The glands in this group can be divided into three groups: Merocrine glands – cells secrete their substances by exocytosis. (e.g. mucous and serous glands; also called "eccrine", e.g. major sweat glands of humans, goblet cells, salivary gland, tear gland and intestinal glands)
The submandibular glands (previously known as submaxillary glands) are a pair of major salivary glands located beneath the lower jaws, superior to the digastric muscles. [6] The secretion produced is a mixture of both serous fluid and mucus , and enters the oral cavity via the submandibular duct or Wharton duct. [ 7 ]
The organ is smaller in proportion to the size of the animal than in most Pleurotomidae. Above, on the dome of the mantle, is attached the rectum, with an evenly tapered adherent termination and a longitudinally wrinkled subcylindrical lumen. To the left of this the muciparous gland and kidney cover a broad strip of the mantle.
The glands and intestinal villi are covered by epithelium, which contains multiple types of cells: enterocytes (absorbing water and electrolytes), goblet cells (secreting mucus), enteroendocrine cells (secreting hormones), cup cells, myofibroblast, tuft cells, and at the base of the gland, Paneth cells (secreting anti-microbial peptides) and ...
