Study Notes
Epithelial Tissue
- Forms a continuous sheet of cells
- Lacks blood vessels (avascular)
- Found covering exterior body surfaces
- Lines internal closed cavities
- Part of glands (secretory portion and ducts)
- Component of sensory receptors
Epithelial Cell Characteristics
- Arranged in sheets
- Contains intercellular junctions (junctional complexes)
- Exhibits distinct surface domains:
- Apical (free) surface
- Lateral surface
- Basal surface
- Surface properties depend on specific membrane proteins
- Rests on a basal lamina
- Non-cellular layer
- Protein-polysaccharide-rich layer
