Bones are an organ that is faithful to the body and that continues to be repaired throughout life. Bone repair involves the removal of mineral bone by osteoclasts followed by the formation of bone in the matrix by osteoblasts which eventually becomes mineral.
The reconstruction cycle consists of three consecutive stages: regeneration, in which the osteoclasts grind the old bone; transformation, in which mononuclear cells emerge from the bone surface; and formation, when osteoblasts lay down new bone until the reconstituted bone is completely replaced.
Bone repair is used to correct bone structure to meet changing mechanical requirements and helps to repair minor damage to the bone matrix to prevent the accumulation of old bone. It also plays an important role in maintaining plasma calcium homeostasis. Orthopedic control is systematic and local. Major systemic regulators include parathyroid hormone (PTH), calcitriol, and other hormones such as growth hormone, glucocorticoids, thyroid hormones, and sex hormones.
Repairing of bone is a process in which mature bone tissue is removed from the bone, it is a lifelong process which is called bone resorption and new bone tissue is formed called ossification or new bone formation. This process is also called bone metabolism and is regulated by maintaining nutrition between osteoblasts and bone resorption by osteoclasts.
Therefore, the correct answer is 'Osteoclast and osteoblast'.
Osteoblasts of bone-producing cells have a great deal of work to do and are responsible for the production of osteoid. They may be inactive bone marrow cells, converted into osteocytes, or disappear with apoptosis.
Osteoclasts are very different from osteoblasts, in terms of their appearance and origin. Osteoblasts and osteoclasts do very different things. Osteoclasts have many nuclear components, meaning cells that have more than one nuclei and a cytoplasm that looks like foam due to the large number of lysosomes and vesicles filled with the enzyme. In addition, the cell membrane adjacent to the skeletal tissue is saturated, which increases the surface area to hide digestive enzymes and absorb the damaged bone tissue.
There are two types of cells that work together to turn your bones into responses to many natural phenomena: osteoblasts and osteoclasts. Bone is a complex matrix made up of calcium phosphate and protein collagen. This matrix is produced and hidden by osteoblasts. Osteoblasts perform bone marrow in response to growth factors and mechanical pressure in the bone.
Opposing osteoblast function is osteoclasts - cells that regenerate bones. Osteoclasts form and release digestive enzymes that break or destroy bone tissue. The osteoclasts then pick up or 'absorb' the bone marrow and continue to break it inside the cell.
