The skeletal system non only includes bones but also tendons, which colligate muscles to bone, and ligaments, which charge bone to bone, and cartilage. Cartilage both resembles and differs from bone. ( Marieb ) Cartilage is much more flexible than bone. The two main types of cartilage are hyaline cartilage and fibrocartilage. Hyaline cartilage is glass like in appearance and mostly coats the ends of bone providing a smooth swerve movement at the joints. Fibrocartilage contains collagen, which giv es it... !
