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.

Mucus is made up of a fluid component of around 95% water, the mucin secretions from the goblet cells, and the submucosal glands (2–3% glycoproteins), proteoglycans (0.1–0.5%), lipids (0.3–0.5%), proteins, and DNA. [7] The major mucins secreted – MUC5AC and MUC5B - are large polymers that give the mucus its rheologic or viscoelastic ...
The Weber's glands are muciparous glands on the side of the tongue. They are a minor salivary gland in the peritonsillar space. They are a minor salivary gland in the peritonsillar space. The glands are named after German anatomist Moritz Ignaz Weber . [ 1 ]
Other mucus-secreting cells are the mucous neck cells in the necks of the gastric glands. [2]: 257 Surface mucous cells have large quantities of mucin granules in their apical (top) surface and project short microvilli into the lumen of the stomach. [2]: 257 Mucins are large glycoproteins that give the mucus its gel-like properties. [3]
These glands secrete mucus to facilitate the movement of particles along the body's various tubes, such as the throat and intestines. The mucosa is the lining of the tubes, like a kind of skin . Submucosal means that the actual gland resides in the connecting tissue below the mucosa.
Goblet cells are simple columnar epithelial cells, having a height of four times that of their width. The cytoplasm of goblet cells tends to be displaced toward the basal end of the cell body by the large mucin granules, which accumulate near the apical surface of the cell along the Golgi apparatus, which lies between the granules and the nucleus.
It receives secretions from the submandibular and sublingual salivary glands. The posterior border of the oral cavity (ie, junction between the oral cavity and the oropharynx) includes the junction of the hard palate and the soft palate superiorly, the circumvallate papillae of the tongue inferiorly, and the retromolar trigone.
