Study Notes
Epithelial Tissue
- Lacking blood vessels (avascular)
- Covers external body surfaces
- Lines internal closed body cavities
- Forms the secretory parts of glands and their ducts
- Makes up the receptors of certain sensory organs
Epithelial Cell Characteristics
- Arranged in sheets
- Possess intercellular junctions (junctional complexes)
- Display distinct surface domains:
- Apical (free)
- Lateral
- Basal
- Properties determined by specific membrane proteins
- Rest on a basal lamina
- Non-cellular
- Protein-polysaccharide-rich layer
