<Tr> <Td_colspan="2"> Anatomical terminology (edit on Wikidata) </Td> </Tr> <P> A tendon or sinew is a tough band of fibrous connective tissue that usually connects muscle to bone and is capable of withstanding tension . </P> <P> Tendons are similar to ligaments; both are made of collagen . Ligaments join one bone to another bone, while tendons connect muscle to bone . </P> <P> Histologically, tendons consist of dense regular connective tissue fascicles encased in dense irregular connective tissue sheaths . Normal healthy tendons are composed mostly of parallel arrays of collagen fibers closely packed together . They are anchored to bone by Sharpey's fibres . The dry mass of normal tendons, which makes up about 30% of their total mass, is composed of about 86% collagen, 2% elastin, 1--5% proteoglycans, and 0.2% inorganic components such as copper, manganese, and calcium . The collagen portion is made up of 97--98% type I collagen, with small amounts of other types of collagen . These include type II collagen in the cartilaginous zones, type III collagen in the reticulin fibres of the vascular walls, type IX collagen, type IV collagen in the basement membranes of the capillaries, type V collagen in the vascular walls, and type X collagen in the mineralized fibrocartilage near the interface with the bone . </P>
