Study Notes
Epithelial Tissues Overview
- Epithelial tissues consist of tightly packed cells that line surfaces and cavities throughout the body.
- Different types of epithelial tissue are classified based on cell shape and number of layers.
Simple Squamous Epithelium
- Found in structures such as the kidney's Bowman’s capsule.
- Functions in filtration and diffusion due to its thinness.
Simple Cuboidal Epithelium
- Located in thyroid acini, where it functions in secretion and absorption.
- Characterized by cube-shaped cells.
Simple Columnar Ciliated Epithelium
- Present in the fallopian tubes.
- Cilia facilitate the movement of substances, such as the movement of the ovum.
Pseudostratified Columnar Ciliated Epithelium
- Located in the trachea, giving it a false appearance of multiple layers.
- Contains cilia that help in trapping and expelling particles and pathogens.
Transitional Epithelium
- Found in the ureter and urinary bladder.
- Specialized to stretch and accommodate fluctuating volumes of liquid.
Stratified Squamous Keratinized Epithelium
- Located in the skin, providing a protective barrier.
- Composed of multiple layers of cells, with the outer layer being keratinized for protection against abrasion.
Stratified Squamous Non-Keratinized Epithelium
- Present in the esophagus, where it provides protection against friction.
- Lacks the outer layer of keratin, making it softer compared to keratinized epithelium.
