FOUR BASIC TYPES OF TISSUES IN THE BODY
-----------------------------------------------
Epithelium Connective tissue
Muscular tissue Nervous tissue
Distinguishing features of epithelium
Always sit on a basement membrane, but come in a variety of configurations: classified on the basis of their shape and of the surface cells and whether one (simple) or more (stratified) layers of cells are stacked upon each other.
These cells are always attached to their neighbors by desmosomes, tight junctions, and gap junctions.
