Study Notes
Types of Epithelial Tissue
-
Squamous Epithelium
- Composed of a single thin layer of flattened cells with irregular boundaries.
- Located in walls of blood vessels and air sacs of lungs.
- Functions primarily in forming a diffusion boundary, allowing substances to pass through.
-
Cuboidal Epithelium
- Made up of a single layer of cube-like cells.
- Commonly found in ducts of glands and tubular structures of nephrons in kidneys.
- Main functions include secretion and absorption.
-
Columnar Epithelium
- Consists of a single layer of tall and slender cells with nuclei located at the base.
- May have microvilli on the free surface, enhancing absorption.
- Found in the lining of the stomach and intestines, aiding in secretion and absorption.
-
Ciliated Epithelium
- Variation of columnar or cuboidal epithelium featuring cilia on the free surface.
- Responsible for moving particles or mucus in a specific direction across the epithelium.
- Mainly present in the inner surface of hollow organs, such as bronchioles and fallopian tubes.
Squamous Epithelium
- Composed of a single thin layer of flattened cells with irregular boundaries.
- Located in walls of blood vessels and air sacs of lungs.
- Functions primarily in forming a diffusion boundary allowing substances to pass through.
Cuboidal Epithelium
- Made up of a single layer of cube-like cells.
- Commonly found in ducts of glands and tubular parts of nephrons in kidneys.
- Main functions include secretion and absorption.
Proximal Convoluted Tubule (PCT) Epithelium
- Features microvilli to increase surface area for absorption.
- Specialized epithelium of the nephron in the kidney.
Columnar Epithelium
- Characterized by a single layer of tall and slender cells with nuclei positioned at the base.
- May have microvilli on the free surface for enhanced absorption.
- Found in the lining of the stomach and intestines.
- Functions primarily in secretion and absorption.
Ciliated Epithelium
- Modified form of columnar or cuboidal epithelium with cilia on the free surface.
- Functions to move particles or mucus in a specific direction across the epithelium.
- Predominantly present in the inner surfaces of hollow organs like bronchioles and fallopian tubes.
