Detailed explanation-1: -Collagen is protein molecules made up of amino acids. It provides structural support to the extracellular space of connective tissues. Due to its rigidity and resistance to stretching, it is the perfect matrix for skin, tendons, bones, and ligaments.

Detailed explanation-2: -The primary connective tissue protein is collagen. Collagen content is often measured in meat to get an estimate of the amount of connective tissue.

Detailed explanation-3: -Bone is a specialized connective tissue that provides the structural framework of the upper extremity.

Detailed explanation-4: -Collagen is principal protein of the skin, tendons, ligaments, cartilage, bone, and connective tissue. Depending upon the degree of mineralization, collagen tissues may be rigid (bone) or compliant (tendon) or have a gradient from rigid to compliant. About one-quarter of all of the protein in our body is collagen.
