Document Summary
Storage place for minerals: calcium, phosphorous, fluoride. Blood clotting: calcium ions participate in the cascade that leads to fibrin (protein involved in blood clotting) Muscle contraction: calcium is released from intracellular muscle stores when stimulated by a nerve impulse, permits the contractile proteins to slide along with each other, which leads to muscle contraction. Cell metabolism: participates in the calmodulin system, calcium entering a cell binds to calmodulin protein, complex activates intracellular enzyme. 65% made up of calcium and phosphorus: provides hardness. 35% made up of organic substances: proteins, collagen, fluids, marrow, blood. Cortical: dense bone tissue, 80% of bone in the body, compact, wrists, hands, feet, outer surface of all bones, long part of the bone, turnover (breaking down and building up) at a slower rate. Womb adolescence: bone growth- length: birth-age 2, first period of rapid growth, females adult height by 14, males adult height by 17, continues to ages 18-21 years of age.
