deep fascia

In stratified epithelia adapted to resist mechanical forces, which of the following types of cell-to-cell junctions are especially abundant?

desmosomes

Which type of tissue covers exposed surfaces of the body?

epithelial

Close examination of an organ reveals a lining of several layers of cells. The layers do not contain any blood vessels and one surface of the cells is open to the internal cavity of the organ. This tissue is probably

epithelium
