Tendon ornithischian dinosaurs, ossified axial muscle tendons form a latticework along the neural and haemal spines on the tail, presumably for support. Tendon A tendon or sinew is a tough band of fibrous connective tissue that usually connects muscle to bone and is capable of withstanding tension. Tendons are similar to ligaments; both are made of collagen. Ligaments join one bone to bone, while tendons connect muscle to bone for a proper functioning of the body. 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
Elastic and inelastic collisions apparatus of the Museo Galileo in Florence. Elastic and inelastic collisions apparatus The elastic and inelastic collisions apparatus is a large apparatus to study elastic and inelastic collisions. It consists of a large frame carrying two beams from which two rows of six and two wooden balls, respectively, are suspended from pairs of strings. The instrument was often used with two elastic balls (of ivory) or inelastic balls (of wet clay), of equal or different mass. By changing the parameters of the experiments such as height of fall and mass, one could conduct a systematic investigation of collision-related phenomena. For example,
