goblet cell
Noun: An epithelial cell that secretes mucus. Goblet cells are specialized glandular cells found within the epithelial linings of various organs, particularly the respiratory and intestinal tracts. Their primary function is to produce and secrete mucin, which forms a protective mucus layer.
Goblet cells are a specific type of cell within a tissue. The term is used in biological, medical, and anatomical contexts. - The lining of the small intestine contains numerous goblet cells. - In chronic bronchitis, there is often an increase in the number of goblet cells in the airways.
- Histological Identification: In microscopy, goblet cells are identified by their distinctive shape—a narrow base and a swollen, cup-like apex filled with secretory granules—which resembles a goblet or wine glass, hence the name.
- Role in Disease: Pathologies like asthma, cystic fibrosis, and ulcerative colitis are associated with abnormalities in goblet cell number (hyperplasia) or function.
- Goblet cell hyperplasia: (Noun Phrase) A condition characterized by an excessive increase in the number of goblet cells.
- Mucous cell: (Noun Phrase) A more general term for a cell that secretes mucus; goblet cells are a type of mucous cell.
- Mucous cell (though this is a broader category)
- Mucocyte (a less common technical term)
There is no direct antonym for a specific cell type. Contextually, one might refer to non-secretory epithelial cells, such as: - Absorptive cell (e.g., an enterocyte in the intestine) - Ciliated cell
- Mucin secretion: (Noun Phrase) The primary product released by goblet cells.
- Epithelium: (Noun) The tissue layer in which goblet cells are found.
- Mucus barrier: (Noun Phrase) The protective layer formed by the secretions of goblet cells and other mucous glands.
