The matrix of fibrous CT consists of fibers. The matrix produced by cartilage cells
appears homogeneous and amorphous. Fat CT has a matrix of lipid.
10.
Two major types of fibrous connective tissue (FCT) are loose areolar FCT, which
is a filling substance around most organs and tissues of the body, and dense FCT,
which is found, for example, in ligaments and tendons. (para 2-9d)
