Joints play an important role in the skeletal system as it helps in permitting the different types of movements at different locations. When the spine has a sideways tilt, or a lateral bend, it is called scoliosis and could be associated with both hyperkyphosis and hyperlordosis. A spinal curvature is when the spine doesnt curve in its usual shape. This shape for the spine is ideally suited for an upright walking posture. For this reason, changes to the concentration of calcium ions have particularly adverse effects on excitable cells in the nervous system, and in cardiac, skeletal and smooth muscle. The calcium in osseous tissue is also an important storage site, that can release calcium when needed. Lateral curvatures (scoliosis) can be severe enough to slip under the shoulder blade (scapula) forcing it up as a hump. It gives the body its shape, allows movement, makes blood cells, provides protection for organs and stores minerals. As we age, the distribution of red and yellow bone marrow changes as seen in the figure (Figure 6.1.2).
