The main component of bone that gives it strength is calcium phosphate. While calcium gives bones strength, collagen is the ingredient that gives bones flexibility. Bone cells replace damaged bone so that they stay strong and healthy.
Bone formation occurs while a person is growing. Because of this, bones grow rapidly in size and strength during childhood and into puberty with little bone loss. When a person reaches the age of 20, bone formation and bone loss tend to even out. At age 30, bone loss occurs more frequently than bone formation.
The three factors needed to keep bones strong are calcium, weight-bearing exercise and vitamin D. Because calcium is crucial for the development and maintenance of bone strength, it is important to eat and drink foods and beverages high in calcium or to take calcium supplements. Bone loss in some older people can lead to osteoporosis. It is also important to take vitamin D as well as to begin an exercise regimen in adolescence and maintain that regimen through the adult years. Postmenopausal women are especially at risk for bone loss. Women can lose up to 20 percent of bone density in their later years as their estrogen levels drop.Learn More
The bones that make up the human skeleton comprise about 15 percent of the body weight. Thus, a 200-pound person has a bone weight of about 30 pounds.Full Answer >
Bones are composed of cortical bone and trabecular bone. Cortical bone is tough and strong, and trabecular bone is less dense than cortical bone and lighter. Bones are also composed of bone-forming cells, collagen, proteins, inorganic mineral salts and bone resorbing cells.Full Answer >
The bony skeleton of the human body provides many vital functions essential to life, but one of the most noticeable is that without bones, an individual could no longer move his body. Muscles contract using bones as levers to move the legs, arms and other body parts.Full Answer >
According to the Museum of Osteology, the study of bones is called osteology, which is practiced by doctors and researchers called osteologists. Osteology is a complex science that uses information and data from anatomy, archaeology and anthropology.Full Answer >
