    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.
