Hyaline cartilage has a very smooth, almost frictionless surface, which allows for smooth, pain-free motion at the joint. The large skull protects the eyes and brains of the bone structure. We are able to control our muscles by sending stimulating impulses via nerves from our brain. Compact bone tissue consists of units called osteons or Haversian systems. Compact bone-(AKA cortical bone) is the dense, hard and very strong bone that forms the protective outer layer of bones. Muscles cannot push against the bone, so muscles typically come in pairs (known as antagonists), one muscle pulls the bone one way and the antagonistic muscle pulls the bone back the other way. Fluid-filled sacs, called bursas, between bones, ligaments, or other nearby structures. c)A fluid-filled cavity is found between the articulating bones. Each muscle has tendon on its end.
