Study Notes
Epithelial Tissue
- The primary function of epithelial tissue is to form the external and internal surface of the body.
Structure and Function
- Epithelial tissue exists in two forms according to its structure and function: simple (single layer) and stratified (multiple layers).
Basement Membrane
- The basement membrane plays a crucial role in epithelial tissue, serving as a thin, flexible layer that separates epithelial cells from underlying connective tissue.
Tissue Types
- Epithelial tissue is characterized by closed packet cells with little or no intercellular material between adjacent cells.
Embryonic Origin
- The liver, pancreas, and lining of the respiratory and gastrointestinal tract originate from the endodermal embryonic germ layer.
- The oral and nasal mucosa, cornea, and skin glands originate from the ectodermal embryonic germ layer.
- The mammary glands originate from the ectodermal embryonic germ layer.
- The uriniferous tubules of the kidney originate from the mesodermal embryonic germ layer.
- The endothelial lining of the circulating system and the mesothelium of the body cavities originate from the mesodermal embryonic germ layer.
