📖 1. Mucosal Membrane Structure and Functions

🔑 Key Concepts & Definitions

• Mucosal membrane : the innermost lining of viscera and some organs, and it generally contains mucus-secreting glands except in the inner lining of blood vessels and the lining of the central nervous system
• Epithelium : the surface layer of the mucosal membrane and performs protection, absorption, secretion, and reabsorption
• Lamina propria : loose connective tissue beneath the mucosal epithelium that contains blood vessels, lymphatic vessels, and sensory and autonomic nerve fibers

★ Must-know

• Mucosal epithelial protection includes defense against mechanical and thermal damage, osmotic effects, dust particles, viruses, bacteria, and parasites, and contributes partly to immune defense.
