Study Notes
Types of Epithelial Tissue
-
Transitional Epithelium
- Specialized type allowing stretching, found in the bladder and parts of the urinary tract.
-
Simple Squamous Epithelium
- Single layer of flat cells; facilitates diffusion and filtration; located in alveoli of lungs and lining of blood vessels.
-
Simple Cuboidal Epithelium
- Single layer of cube-shaped cells; functions in secretion and absorption; common in kidney tubules and glands.
-
Pseudostratified Columnar Epithelium
- Appears stratified but is a single layer; often ciliated; found in the respiratory tract, aiding in secretion and movement of mucus.
-
Simple Columnar Epithelium
- Single layer of tall cells; involved in absorption and secretion of mucus and enzymes; lining of the stomach and intestines.
-
Stratified Squamous Epithelium (Keratinized)
- Multiple layers of flat cells; provides protection, particularly in areas exposed to abrasion, such as skin.
-
Stratified Squamous Epithelium (Nonkeratinized)
- Similar to keratinized but lacks surface keratin; found in moist areas such as the mouth, esophagus, and vagina.
-
Stratified Columnar Epithelium
- Multiple layers of cells with columnar shape on the surface; found in male urethra and some glandular ducts.
-
Stratified Cuboidal Epithelium
- Usually two layers of cube-shaped cells; provides protection and is rare, found in some sweat glands and mammary glands.
Key Characteristics
- Epithelial tissues have minimal extracellular material, allowing tight cell connection.
- Serve essential roles in protection, absorption, secretion, and sensation.
- Can be classified by the number of layers (simple vs. stratified) and cell shape (squamous, cuboidal, columnar).
