Definition
  1. Noun:
    • A protective secretion produced by mucous membranes: "Mucous secretion" refers to the viscous, slippery fluid secreted by mucous membranes lining various cavities and passages in the body.
    • A lubricating and protective substance: It serves to lubricate surfaces, protect epithelial cells, and trap pathogens or particles.
Usage Examples
  • Noun:
    • The respiratory tract produces mucous secretion to trap dust and microbes.
    • Excessive mucous secretion is a common symptom of a cold or allergy.
    • The primary function of gastric mucous secretion is to protect the stomach lining from acid.
Advanced Usage
  • "Mucous secretion" in medical contexts: Often discussed in relation to hypersecretion (overproduction) or changes in viscosity.
    • Chronic bronchitis is characterized by increased and thickened mucous secretion.
  • "Mucous secretion" as a barrier: Describes its role in innate immunity.
    • The mucous secretion forms a physical barrier that is difficult for many bacteria to penetrate.
Variants and Related Words
  • Mucus (n): The name for the substance itself, often used interchangeably in general contexts, though "mucous secretion" refers more specifically to the act or product of secreting it.
    • Mucus is composed of water, glycoproteins, and salts.
  • Mucous (adj): Of, relating to, or resembling mucus.
    • The mucous membrane was inflamed.
  • Mucin (n): The key glycoprotein that gives mucous secretion its viscous, gel-like properties.
    • Mucins are the primary macromolecular components of mucous secretion.
Synonyms
  • Mucus: The slimy, viscous substance.
  • Phlegm: Mucus specifically from the respiratory tract, often expelled by coughing.
  • Sputum: A mixture of saliva and mucus coughed up from the respiratory tract.
Related Phrases
  • Mucous membrane: The epithelial tissue that secretes mucus.
    • The inside of the mouth is lined with a mucous membrane.
  • Mucociliary clearance: The process by which cilia move mucous secretion (and trapped debris) out of the airways.
    • Smoking can impair mucociliary clearance, leading to mucus buildup.
Related Concepts
  • Goblet cell: A specialized epithelial cell that secretes mucin, a major component of mucous secretion.
    • Goblet cells are responsible for the production of much of the intestinal mucous secretion.
  • Serous secretion: A contrasting, typically thinner and more watery bodily secretion, often produced alongside mucous secretion in glands.
    • The salivary glands produce both serous and mucous secretions.
