Study Notes
Epithelial Tissue Types
-
Simple Squamous Epithelium
- Composed of a single layer of flat cells
- Function: Facilitates diffusion and filtration
- Location: Found in alveoli of lungs and lining of blood vessels
-
Simple Cuboidal Epithelium
- Consists of a single layer of cube-shaped cells
- Function: Secretion and absorption
- Location: Forms the walls of kidney tubules and ducts of small glands
-
Simple Columnar Epithelium
- Made up of a single layer of tall, column-like cells
- Function: Absorption and secretion of mucus and enzymes
- Location: Lines the stomach, intestines, and some glands
-
Stratified Squamous Epithelium (Non-Keratinized)
- Characterized by multiple layers of flat cells
- Function: Protects underlying tissues in areas with abrasion
- Location: Found in the lining of the mouth, esophagus, and vagina
-
Pseudostratified Columnar Epithelium
- Appears to have multiple layers due to differing cell heights but is actually a single layer
- Function: Secretion and movement of mucus
- Location: Found in the respiratory tract, including the trachea
-
Transitional Epithelium
- Specialized to stretch and change shape
- Function: Allows for distension of urinary organs
- Location: Lines the bladder, ureters, and part of the urethra
-
Transitional Stretched Epithelium
- Represents the transitional epithelium in a stretched state
- Function: Accommodates fluctuations in volume within the urinary system
- Location: Found in the same regions as normal transitional epithelium, specifically when the bladder is full
