Every muscle has an interwoven connective tissue that attaches the muscle fibers and bundles together. If you picture muscles as a large, ornate stained glass window, the fibers and bundles would be the different sized colorful glass panels. The surrounding and supporting connective tissue would be the surrounding and supporting lead in the windows. This connective tissue, which looks like steak gristle in large bundles, is composed of collagen strands that give it a tremendous ability to withstand pulling or longitudinal strains. It also has limited elasticity, which allows it to stretch while still holding the tissues together. Without the connective tissue holding the muscles together, you would lose your strength and the ability to move your bones or support your frame.
