Osteoblasts In Bone Formation

Improved Essays
1. Describe Ossification during Fetal Development.
During the fetal development the first stage of the “bones” is cartilage which resembles bones but is more flexible due to the lack of calcium salts as it develops calcium salts are deposit into it all through until after it is born to life. As a result, the process of gradual replacement of immature bone cells and calcium deposits is called Ossification.
2. What are the roles of Osteoclasts in bone formation?
The roles of Osteoclasts in bone formation are as follows, the suffix –clast is from the Greek word meaning to break. Therefore, Osteoclasts are large cells that function to reabsorb, or digest, bony tissue. It does so by digesting bone tissue from the inner sides of the bones thus enlarging the inner bone cavity so that the bone does not become overly thick and heavy.
3. How do Osteoblasts assist when recovering from a fractured bone?
Osteoblasts assist in the recovery from a fractured bone by laying down the bone matter (calcium salts) there after osteoclasts moves in to remove excess bone debris. Osteoclasts and Osteoblasts work as a team, one breaks down the other repairs.
4. How does Vitamin D support bone formation?
Vitamin D supports bone formation by helping the calcium in our bodies pass through the lining of the small intestine and into our

Long bones: are found in the thigh, lower leg, and upper and lower arm. They are very strong, broad at the ends where they join with other bones, and have a large surface areas for muscle attachment. Short bones: are in the wrist and ankles and are small with irregular shapes. Flat bones: cover soft body parts like the skull, shoulder, ribs, and pelvic bones. Sesamoids bones: are small, rounded bones ex. a sesame seed in shape. They are found near joints and aid in muscle

    Intramembranous bone formation, also known as ossification, is how flat bones develop from mesenchyme tissue. In this method of bone formation, there are four major steps in the developing process. In the first step, the ossification center forms by osteoblasts. These osteoblasts are created from stem cells within the mesenchyme that specialize. In the second step the osteoblasts from the ossification center produce proteins make up the osteoid. After the osteoid if formed it will combine with calcium…

    Micro-fracture consolidation can be treated with bone remodeling, and the adaptation of skeleton is applied to “calcium homeostasis” and to mechanical use. The bone remodeling involves the bone resorption regarding to osteoclasts and bone formation relating to osteoblasts. Regular bone-related diseases including “bone-metastasized cancers”, Paget’s disease, multiple myeloma, and osteoporosis are caused by the disproportion between the resorption and formation processes. The increased deterioration of health…

    There are two processes of development of the bone from fertilisation to adulthood and are intramembranous and endochondral ossification. Intramembranous ossification takes place throughout the flat bone of the skull. It is also responsible for developing jaws, clavicles and collar bones. A development starts after mesenchymal cells in the embryonic skeleton collect together and distinguish into osteoblasts, developing an ossification centre. Osteoblasts start to secrete osteoid and are calcified in…
