Hint: Human skeleton, an inner skeleton that lays the groundwork for the body. This structure is made of several bones in the body, cartilage, tendons, and ligaments, and contributes to about 20% of body mass.
Complete answer:
Calcium is a chemical compound that cannot be formed by any biological mechanism. The only means that can reach the body would be through a diet. Bones function as a storage location for calcium: the body preserves calcium in the bones if blood levels are too high and shed calcium when blood levels have dropped too low. Skeletal muscle function is regulated by the potential for action that triggers the calcium contained within the sarcoplasmic reticulum. This calcium subsequently binds to tropomyosin which enables the interaction of actin and myosin in the sarcomere, corresponding to muscular contractions. Despite their toughness and strength, the bones suffer from disease and injury. Bone disorders entail breaks, osteoarthritis, and rickets. Rickets is a bone softening that happens since bones will not have enough calcium. Rickets can lead to breaks and bowing of bones of the leg. Other reasons can include inadequate calcium or phosphorus. The role includes a lack of calcification of skeletal plates. Calcitriol controls the levels of calcium and phosphorus in the bloodstream and helps support a balanced skeletal system. As the concentration of calcium in the blood rises, the parafollicular cells of the thyroid gland enhance the secretion of calcitonin in the blood. At the very same time, parathyroid glands limit the secretion of thyroid hormones in the blood. Calcium removal from bone is also hindered. If the calcium level of the blood is too poor, the secretion of calcitonin is blocked and the secretion of PTH stimulated. This involves the removal of calcium from bone to correct blood calcium levels.
Additional Information:
When blood calcium levels have dropped more than average, calcium is expelled from the bones and provides an adequate supply for metabolic requirements. Once blood calcium levels rise, surplus calcium is accumulated in the bone matrix. The complex mechanism of calcium release and storage continues nearly endlessly.
Note:
Bones provide such a rigid structure, recognized as the skeleton, that surround and support the soft organs of the body. The skeleton helps to protect the body against the pull of gravity. When standing, the large bones of lower limbs reinforce the spine.
