Several key surface structures are commonly studied in histology:
- Microvilli: Finger-like projections that increase surface area for absorption, commonly found in the intestinal epithelium. - Cilia: Hair-like structures that move fluid across the cell surface, prominent in the respiratory tract. - Glycocalyx: A carbohydrate-rich layer that protects and facilitates cell recognition and adhesion. - Desmosomes and Tight Junctions: Specialized cell junctions that maintain tissue integrity and regulate paracellular transport.
