Three types of connecve ssue form the principal components of the
skeletal system: fibrous connecve ssue, carlage, and bone. Despite being made
up of similar cells, these components differ in the nature of the matrix that is
laid down between individual cells.

Fibrous connective tissue is the most common type of connecve ssue
in the body of vertebrates. This ssue consists of flat, irregularly branching cells
called fibroblasts that produce structurally strong proteins into the spaces
between the cells. The strength of this ssue is dependent on the type of
proteins they contain. Loose connective tissues, found beneath the skin and
other epithelial ssues, provide the least amount of strength. The dense
connective tissues of tendons provide flexible and strong connecons. Elastic
connective tissues located in the ligaments, large arteries, lungs, and skin
provide strength and the ability to stretch and recoil.
