Study Notes
Simple Epithelial Tissue
- Simple epithelial tissues are one cell layer thick on a basement membrane.
- There are three main types: simple squamous, cuboidal, and columnar.
- Simple squamous epithelial tissue is the thinnest lining and is found in areas where there is no friction and substances need to pass through the tissue wall.
- Examples of where simple squamous epithelial tissue is found include blood vessel walls and ureters.
- Cuboidal epithelial tissue is found in kidney tubules and oviduct.
- Columnar epithelial tissue often has cilia lining its free surface and is called ciliated columnar epithelial tissue.
- Single-celled glands, called goblet cells, produce mucus, which is moved along by the cilia in columnar epithelial tissue.
- This 'conveyor belt' system is useful in places such as the nasal cavity, liver, and digestive tract.
Compound Epithelial Tissue
- Compound epithelial tissues are more than one-cell-layer thick on a basement membrane.
- There are two main types: stratified squamous and transitional.
- Stratified squamous epithelial tissue is found in areas subject to trauma, such as the oral cavity, esophagus, and skin.
- The skin has been infiltrated by keratin, which makes it appear different.
- Different areas of the skin are more keratinized than others, such as foot pads.
- Transitional epithelial tissue is found in the bladder and urethra.
- Transitional epithelial tissue has the ability to expand greatly, which is useful as the bladder fills with urine.
- When the bladder fills, the number of cell layers is greatly reduced.
