The uses of the bones may be classed under three divisions : First, for a framework to the whole system. Second, to furnish points of attachment to muscles and ligaments. Third, to protect the softer parts. 165. A Framework. Ligaments used as Braces and Pins. —Exactly as a human architect plans and constructs a frame to the house, so the Great Architect has formed the bones. Each bone is fitted exactly to the position, size, and use of the part where it is placed, and nowhere can a supernumerary bone be found. In the house to be built, braces and joining pins must be employed, and those generally of a tougher material than the frame itself. So in the human body, liga- Why is cartilage useful in the lubrication of joints ? 164. Give the uses of the bones as classed above. 165. Compara the bones and ligaments with the timbers, braces and pins of a house. Fig. 94.
