Document Summary

The following information identifies a few select features of connective tissue: nerve supply. Most connective tissues have a nerve supply (as does epithelial tissue): blood supply. There is a wide range of vascularity among connective tissues, although most are well vascularized (unlike epithelial tissues, which are all avascular): structure. Connective tissue consists of scattered cells immersed in an intercellular material called the matrix. The matrix consists of fibers and ground substance. The kinds and amounts of fiber and ground substance determine the character of the matrix, which in turn defines the kind of connective tissue: cell types. Fundamental cell types, characteristic of each kind of connective tissue, are responsible for producing the matrix. Immature forms of these cells (whose names end in blast) secrete the fibers and ground substance of the matrix. Matrix fibers are proteins that provide support for the connective tissue.
