Mucous glands produce and secrete mucus, which serves several important functions in the body. Mucus acts as a protective barrier, lubricating surfaces and trapping pathogens, dust, and other foreign particles to prevent them from entering the body. It also aids in the movement of food through the digestive tract and keeps tissues moist, facilitating various physiological processes. Additionally, mucus plays a role in immune defense by containing antibodies and enzymes that help neutralize harmful microorganisms.
Mucous-secreting glands are primarily found in epithelial tissues. These glands are commonly located in the respiratory tract, digestive tract, and certain parts of the reproductive system. For example, goblet cells in the respiratory and intestinal epithelium secrete mucus to protect and lubricate surfaces. Additionally, mucous glands can be found in salivary glands and the gastric mucosa of the stomach.
Brunner's glands secrete an alkaline mucous substance that helps neutralize stomach acid and protect the mucosal lining of the duodenum from damage. These glands also aid in digestion by providing lubrication for the passage of food and enzymes.
The parotid, submandibular, and sublingual glands are the three major salivary glands in the human body. The parotid glands are the largest, located near the ears, and primarily produce serous (watery) saliva. The submandibular glands are found beneath the jaw and produce a mixed secretion of serous and mucous saliva, while the sublingual glands, located under the tongue, mainly produce mucous saliva. Together, these glands play a crucial role in digestion, oral health, and maintaining moisture in the mouth.
NO. sublingual gland is mucous salivary exocrine gland.
The parotid, submandibular, and sublingual glands are the three major salivary glands in the human body. The parotid glands are the largest, located near the ear, and primarily produce a serous, enzyme-rich saliva. The submandibular glands are found beneath the jaw and produce both serous and mucous saliva, while the sublingual glands, located under the tongue, primarily secrete mucous saliva. Together, these glands play a crucial role in digestion and oral health by lubricating food and aiding in its breakdown.
Mucus is the thin, sticky film produced by the mucous glands.

Mucous, made by mucous glands, stick to the cilia of cells that are found in the mucous membranes.

Sinus infections primarily affect the mucous membranes of the sinus cavities rather than a specific gland. However, the sinuses are closely associated with the nasal passages and the mucous glands that produce mucus. Inflammation and infection can lead to increased mucus production, contributing to congestion and pressure in the affected areas. While the sinuses themselves are not glands, their function is intertwined with the mucous glands in the respiratory system.
Some salivary glands produce both mucous and serous secretions, and these are called "mixed" glands. -Pasqualino P.
Mucous glands
The cells that secrete mucus are the goblet cells. They are not considered glands and there are no glands that are mucous.
Buccal glands (or genal glands) are mixed glands in the mucous lining of the cheeks of mammals, except aquatic forms.
