Mucilage is edible. It is used in medicine as it relieves irritation of mucous membranes by forming a protective film. It is known to act as a soluble, or viscous, dietary fiber that thickens the fecal mass, an example being the consumption of fiber supplements containing psyllium seed husks. [5]
A mucous membrane or mucosa is a membrane that lines various cavities in the body of an organism and covers the surface of internal organs. It consists of one or more layers of epithelial cells overlying a layer of loose connective tissue .
Mucous cells of the stomach lining secrete mucus (pink) into the lumen. Mucus (/ ˈ m j uː k ə s /, MEW-kəs) is a slippery aqueous secretion produced by, and covering, mucous membranes. It is typically produced from cells found in mucous glands, although it may also originate from mixed glands, which contain both serous and mucous cells.
This important relationship is known to affect 94% of land plants, [11] and benefits plants by increasing water and nutrient uptake from the soil, particularly phosphorus. In return, the fungi receive food in the form of carbohydrates from the plant in the form of broken-down root mucilage. Without this relationship, many plants would struggle ...
Fusion of the vesicles to the plasma membrane causes release of the mucin, which as it exchanges Ca 2+ for Na + expands up to 600 fold. The result is a viscoelastic product of interwoven molecules which, combined with other secretions (e.g., from the airway epithelium and the submucosal glands in the respiratory system), is called mucus. [22] [23]
In medicine, astringents cause constriction or contraction of mucous membranes and exposed tissues and are often used internally to reduce discharge of blood serum and mucous secretions. [8] This can happen with a sore throat , hemorrhages , diarrhea , and peptic ulcers .
As its Latin name indicates, it is a characteristic component of the mucosa, or the mucosa's "own special layer." Thus, the term mucosa or mucous membrane refers to the combination of the epithelium and the lamina propria. [1] The connective tissue of the lamina propria is loose and rich in cells.
A demulcent (derived from the Latin: demulcere "caress") is a mucilaginous or oleaginous preparation [1] that forms a soothing protective film over a mucous membrane, relieving minor pain and inflammation of the membrane. [2] However, they generally help for less than 30 minutes. [3] Demulcents are sometimes referred to as mucoprotective agents.
