Introduction:
One-third of the connective tissue is the bone, and are they are impregnated with salts of calcium constituting two-third of parts. The inorganic calcium salts, majorly calcium phosphate and partially calcium carbonate, and traces of other salts make the bone rigid and hard to afford resistance to compressive forces of weight-bearing and impact forces of jumping. The collagen fibers present in bones make it tough and flexible that can afford resistance to tensile forces.
The humerus is the arm bone and is the longest bone of the upper limb. It comprises an upper end, shaft, and lower end.
