Bone remodeling allows bones to adapt to stresses by becoming thicker and stronger when subjected to stress.

Bones that are not subject to normal stress, for example when a limb is in a cast, will begin to lose mass. A fractured or broken bone undergoes repair through four stages:.

Question: What effect does the removal of calcium and collagen have on bone structure? Background: Conduct a literature search on the role of calcium and collagen in maintaining bone structure.

Conduct a literature search on diseases in which bone structure is compromised. Hypothesis: Develop a hypothesis that states predictions of the flexibility, strength, and mass of bones that have had the calcium and collagen components removed. Develop a hypothesis regarding the attempt to add calcium back to decalcified bones. Test the hypothesis: Test the prediction by removing calcium from chicken bones by placing them in a jar of vinegar for seven days.

Test the hypothesis regarding adding calcium back to decalcified bone by placing the decalcified chicken bones into a jar of water with calcium supplements added. Analyze the data: Create a table showing the changes in bone flexibility, strength, and mass in the three different environments. Report the results: Under which conditions was the bone most flexible? Under which conditions was the bone the strongest?

Draw a conclusion: Did the results support or refute the hypothesis? How do the results observed in this experiment correspond to diseases that destroy bone tissue? Ossification is the process of bone formation by osteoblasts. Long bones lengthen as chondrocytes divide and secrete hyaline cartilage. Osteoblasts replace cartilage with bone. Appositional growth is the increase in the diameter of bones by the addition of bone tissue at the surface of bones.

Bone remodeling involves the processes of bone deposition by osteoblasts and bone resorption by osteoclasts. Bone repair occurs in four stages and can take several months. Improve this page Learn More. Skip to main content. Module The Musculoskeletal System. Search for:.

Decalcification of Bones Question: What effect does the removal of calcium and collagen have on bone structure? In time, the encased cartilage cells die. As they die, the cartilage cells leave behind tiny pockets in the bone. Blood vessels grow into these pockets and deposit specialized cells, known as osteoblasts, into the empty spaces.

Osteoblasts perform a number of functions that help bones grow. These cells help to collect calcium into the pockets, which helps encase even more cartilage cells. Osteoblasts also produce a substance that is rich in collagen fibers that help create the structure of bone. When the osteoblasts finish building new bone, they become flat and resemble pancakes.

These flattened cells line the surface of the bone and regulate how much calcium passes into and out of the bone. Keeping the right amounts of calcium and other minerals in bone is important to maintaining strong bones; low calcium levels decreases bone density, which increases the risk of bone fractures.

Newborn babies have large amounts of cartilage in their bones, particularly at the ends of the bones in areas known as "growth plates. The cartilage continues to grow as the bones grow.

The presence of a growth plate indicates that the bone is still growing. The ossification process is typically complete by the time a person reaches his or her mids , when their bones are as long as they will ever be. Bone continues to change over the course of a person's lifetime. While they do not grow longer, for example, bones can become thicker during adulthood.

Bone thickening is often in response to increased muscle activity, such as weight training. Bones can also heal and repair themselves. After bones stop getting longer, they continue to produce new bone tissue to replace old bone tissue.

In fact, the adult body replaces its skeleton every 7 to 10 years. Bones contain living tissue that renews itself regularly in a process known as bone turnover. The process happens in two stages. First, osteoblasts draw calcium from the bloodstream to build new bones. Next, cells known as osteoclasts dissolve the bone and return the calcium to the bloodstream.
