Study Notes
Epithelial Tissue Overview
- Epithelial tissue functions include protection, secretion, and absorption.
- Two main types: simple (single layer) and stratified (multiple layers).
- Stratified epithelium found in areas subjected to abrasion, while simple epithelium is involved in absorption and filtration.
Types of Epithelium
- Transitional epithelium allows stretching, found in bladder.
- Columnar epithelium, which may contain microvilli, increases surface area for absorption.
- Specialized glandular epithelial cells secrete substances like enzymes and hormones.
Physical Connections in Tissues
- Desmosomes provide structural support by anchoring adjacent cells.
- Gap junctions facilitate cell communication and nutrient exchange between adjacent cells.
- Endothelium lines blood vessels, acting as a barrier between blood and connective tissue.
Functionality in Disease
- Epithelial tissues can act as barriers that prevent the flow of nutrients between connective tissues and epithelium.
- Disruption in epithelial function can contribute to disease progression.
Specialized Structures
- Nephron epithelium functions in filtration in kidneys; features specialized cells with microvilli for increased absorption.
- Salivary glands consist of epithelial cells that produce and secrete saliva.
Importance of Locations
- Locations of epithelial tissue types correlate with their functions; for example, stratified squamous epithelium is found in skin for protection.
- Simple cuboidal epithelium is typically present in glands and ducts for secretion.
Histological Techniques
- Histology provides insights into tissue structure and function through microscopic examination.
- Various staining techniques help visualize specific features of epithelial tissues.
Autonomic Functions
- Epithelial tissues respond to autonomic stimulation, impacting functions such as secretion in saliva glands.
Key Terms
- Keratin: A protein that provides strength and waterproof properties to certain epithelial cells.
- Stratified columnar epithelium aids in secretion and is rare, found in some gland ducts.
Epithelial Adaptations
- Epithelial cells adapt to their environment, with variations in shape and structure (e.g., keratinized layers in skin).
- The anatomy of epithelium allows unique functionalities tailored to their roles in the body.
