Slimhinner

Slimhinner is the Norwegian term for mucous membranes, the moist linings of cavities and passageways that connect with the external environment. The term is used to refer to the mucosal surfaces of the respiratory, digestive, urogenital tracts, and the ocular surface, among others. In anatomical writing, slimhinner describes tissues composed of epithelium overlying lamina propria, with mucus-producing goblet cells and, in parts of the respiratory tract, ciliated cells that help clear debris.

Function: Mucous membranes protect internal tissues from pathogens, provide lubrication, and perform secretion or absorption in specific tracts. Mucus produced by goblet cells traps particles and contains antibodies and enzymes that contribute to immune defense. The epithelium and underlying tissues are often supplied with rich blood vessels to support secretions and transport.

Distribution: Mucous membranes line the nasal and oral cavities, sinuses, pharynx, larynx, trachea and bronchi, the stomach, intestines, and parts of the urinary and reproductive tracts, as well as the conjunctiva of the eye.

Clinical considerations: Mucosal surfaces can be affected by dryness, infections (for example rhinitis, conjunctivitis), inflammatory diseases, autoimmune conditions, and injuries. They are central to mucosal immunity and are a frequent site of pathogens entering the body.

Name origin: In Norwegian, slimhinnen or slimhinner refers to the mucous membranes; the term slimhinner is the plural form. See also mucous membrane and mucosa for broader context.
