Detailed explanation-1: -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.

Detailed explanation-2: -Ligaments are made out of connective tissue that has a lot of strong collagen fibers in it. They are found in different shapes and sizes in the body. Some look like pieces of string, others look like narrow or wide bands.

Detailed explanation-3: -The solid components of ligaments are principally type 1 collagen (image is of the triple helix, collagen) which accounts for approximately 75% of the dry weight with the balance being made up by proteoglycans (<1%), elastin and other proteins and glycoproteins.

Detailed explanation-4: -The ligament is the fibrous connective tissue that connects bones to other bone. Ligaments are made out of white fibrous connective tissue and some yellow fibrous connective tissue. They are found in different shapes and sizes in the body.

Detailed explanation-5: -Elastin is a highly extensible structural protein network that provides near-elastic resistance to deformation in biological tissues. In ligament, elastin is localized between and along the collagen fibers and fascicles.
