which of the following are usually present in connective tissue
Connective tissue comprises one of the four basic tissue types. The others are: epithelial tissue (surfaces and glands), muscle tissue (contractile cells), and nervous tissue. Organs represent various combinations of these four basic tissue types, which thus comprise the entire body.he extracellular fibers of connective tissue are traditionally classified into three types: 1  Collagen fibers confer main tensile strength, and are the stuff of scars. 2  Elastic fibers confer elasticity. 3  Reticular fibers (really, a special form of collagen) provide a delicate supporting framework for loose cells.
