Study Notes
Epithelial Tissue Types and Locations
-
Simple Squamous: A single layer of flattened cells. Found in the lungs (air sacs) and lining blood vessels. Its function facilitates diffusion and filtration.
-
Stratified Squamous: Multiple layers of flattened cells. Provides protection from wear and tear and is crucial in areas of high abrasion. Found in the skin and mouth lining.
-
Simple Cuboidal: A single layer of cube-shaped cells, with spherical nuclei. Commonly found in the kidney tubules and glands' ducts, primarily involved in secretion and absorption.
-
Simple Columnar: A single layer of rectangular, elongated cells. Located in the digestive tract, these cells are vital for secretion and absorption.
-
Pseudostratified Columnar: A single layer of irregularly shaped cells, some cells appear to be tiered. Giving a false impression of multiple layers. Found lining the respiratory system (air passages) and the reproductive tract.
-
Transitional Epithelium: Multiple cell layers that switch shape. Cuboidal when relaxed and squamous when stretched. Found in organs of the urinary system, including the bladder, to accommodate fluctuations in volume.
Key Epithelial Tissue Characteristics
-
Simple vs. Stratified: Simple epithelium comprises a single layer, while stratified epithelium consists of multiple cell layers.
-
Cell Shape: Epithelial cells are classified based on their shape. Types include squamous (flat), cuboidal (square), and columnar (elongated).
