    Calcium Functions

    Bone
    Calcium forms a salt called calcium phosphate, which helps to make bones hard and rigid. These salts are deposited in the matrix of cartilage in early life of most animals to form solid bone. The bone also acts as a calcium reservoir from which calcium can be removed or deposited as necessary.

    Muscle
    In muscle, calcium is needed for contraction. In resting muscle, the actin binding sites on myosin are blocked by tropomyosin. When calcium binds to tropomyosin, it moves it away from the bindins sites, allowing actin to bind to myosin and thus ...

    Solution Summary

    The goal in this solution is to understand the varied roles of calcium in the skeletal, muscular and nervous systems. The solution also looks at the regulation of calcium.
