Study Notes
Epithelial Tissue
- The primary function of epithelial tissue is to form the lining of organs, glands, and other body surfaces, and to regulate the flow of materials across these surfaces.
Characteristics of Epithelial Cells
- Epithelial cells are characterized by being tightly packed, with minimal intercellular material, and are often connected by specialized junctions.
Specialization of Epithelial Cells
- The process by which epithelial cells become specialized to perform specific functions is called differentiation.
Location of Epithelial Tissue
- Epithelial tissue is typically found in the body lining organs, glands, and other body surfaces, such as the skin, lungs, gut, and glands.
Function of Basement Membrane
- The basement membrane is a thin layer of extracellular matrix that separates epithelial tissue from underlying connective tissue, and plays a crucial role in maintaining tissue structure and function.
