Bone Formation Of Blood Cells

What are the roles of osteoclasts in bone formation? Osteoclasts are large cells that function to reabsorb, or to digest bone tissue. They digest bone tissue from the inner sides of bones thus enlarging the inner bone cavity so that the bone does not become overly thick and heavy.

Throughout life the skeletal system is constantly changing. Bone modeling, formation and growth of bones, occurs from birth to early adulthood resulting in increase in skeletal mass and changes in skeletal form. Naturally the peak bone mass is achieved in the third decade of life, meaning the bones are at their strongest state in human development. Bone remodeling, a response to micro trauma and stress on the bone, is a dynamic process that also occurs through life. Bone is composed of collagen type 1, a protein, minerals such as calcium and phosphate and bone forming cells (osteoblasts and osteocytes) as wells as bone resorbing cells known as osteoclasts. Calcium is a main contributor of bone strength. In fact 99% of calcium is stored in bones and teeth with one percent remaining in the blood. The process of bone remodeling is activated by stressors such as weight bearing and is necessary to maintain bone mass in an adult. It’s a dynamic process in which bone resorption is always

Bones are dynamic tissues that undergo a constant cycle of fracturing, resorbing, and remodeling. Bone mass is reflected by the coupled balance of osteoblasts, which produce bone matrix proteins and osteoclasts, which degrade bone (Miyamoto, 2003). This opposite and complementary activity between these two lineages of cells maintains the homeostasis of bone resorption and formation during bone remodeling. Dysregulation of this process is a major mechanism in the pathogenesis of many human skeletal disorders such as osteoporosis and osteochondroma (Edwards, 2012).

The trabecular bone is a form of osseous tissue that is found in the proximal and distal ends of long bones, along with the bones of the skull, pelvis, ribs and the vertebral bodies. The trabecular bone undergoes remodeling every two to eight months in order to accommodate the load of physiological stress and mechanical forces on the bone (Huiskes et al. 2000). Bone remodeling is the reshaping or replacement of bone during growth and following injuries such as fractures, but it also occurs in cases of micro-damage (Kini and Nandeesh, 2012). This supports Wolff’s Law, which states if loading on a particular bone increases, the bone will remodel over time to strengthen itself to resist that type of loading (Frost, 1994) The use of trabecular

Bones are dynamic tissues that undergo changes need to maintain bone and calcium homeostasis through a process called bone remodeling. Bone remodeling is an essential process that repairs damaged bone and maintains mineral homeostasis. This process is regulated by two main cells that perform opposite, but complementary function. Osteoblasts are the main bone forming cells that originate from mesenchymal stem cell lineage. Osteoblasts produce bone matrix which they later mineralized to form bone. During the process of bone formation, matured osteoblasts usually get trapped in the bone matrix and become osteocytes. Osteoclasts on the other hand, are the main bone resorbing cells; they resorb bone producing proteolytic enzyme and acid. In response

As the remodeling process that conducts by both of the cells is unstable, the bone tissues are affected too. Bones consists of two types of bones tissue which is compact bone and spongy bone. Compact bone also known as cortical bone is the hard outer layer of the bone and it is found beneath the periosteum. It provides support and protection and withstands the stress produce by weight and movement. Meanwhile, spongy bone also called as trabecular or cancellous bone is usually found at the end of the long bones. The spongy bone tissues have a honey-comb like structure. In osteoporosis, the bones tissue start to break down faster than it can regenerate. Hence, the bones tissue slowly lose their density and becomes thinner. Plus,the holes structure

Bone remodeling is a five-stage process. Bone is renewed to prevent accumulation of micro-damage and maintain bone strength and BMD (Burr,

Calcium, often called the body's building block, is needed to develop strong, healthy bones and teeth. In some cases, pediatricians may recommend calcium supplements.

Bone remodeling is required to repair old the bone and to prevent the aging effects and its consequences. This process requires balance between bone formation and bone resorption and direct communication among different bone cells. Cells of the osteoblast lineage (osteoblasts, osteocytes) and bone-resorbing cells (osteoclasts), together with their precursor cells, are organized in specialized units called bone/basic multicellular units (BMU) (145). We have already detailed the origin of osteoblasts, responsible for bone matrix synthesis and its subsequent mineralization, and osteoblasts-derived osteocytes. On the other hand osteoclasts are large, multinucleated giant cells formed from the fusion of mononuclear progenitors of the monocyte/macrophage

Calcium is central to the factor for body which will help in building up bones as well as it encourages the health and fitness of the body. A lot of doctors proves that Getting sufficient calcium from the child years through adulthood allows build bones up then helps slow losing bone as we grow older. The dairy items aren't the better source.

The function of all three help is to maintain calcium homeostasis and provide enough calcium to effectively maintain bone strength. In an depth analysis on bone and bone structure; the dynamics of calcium homeostasis are simplified; “When blood calcium levels decrease below normal, calcium is released from the bones so that there will be an adequate supply for metabolic needs. When blood calcium levels are increased, the excess calcium is stored in the bone matrix. The dynamic process of releasing and storing calcium goes on almost continuously, and is carried out by different bone cells” (Gray-Wilson & Wilkin, 2016, p. 9). Osteoblasts assist this calcium homeostasis by forming into osteocytes when trapped in the bone matrix, and cause the under stimulation of the production of osteoid. With less focus on the production osteoid, attention is directed to the production of calcium and the directing of calcium into the blood where it is transported to provide for numerous functions in various other systems of the body. When calcium levels begin to decrease again, the cycle begins anew when osteoclasts break down the bone matrix to dissolve calcium

our bones are continuously rebuilding and reforming. Our bodies use 99% of its calcium to keep

Both the osteoblast and osteoclast plays a role in this process. The osteoblast produces new bone tissue whereas the osteoblast resorbed older bone tissue. Bone remodeling are assisted by vitamin A, C and D, and minerals such as calcium, phosphorus and magnesium. It also requires the secretions of calcitonin, growth and parathyroid hormones. The cycle continues until adolescence

Bone health maintenance is important in combating osteoporosis. Achieving peak bone mass during adolescence and maintaining this throughout life enhance bone health. This disease is among the leading cause of morbidity in industrialized countries [3]. Calcium has long been recognized as an important factor for the maintenance of bone health.

What concerned researchers was the fact that while calcium intake is widely promoted for better bone health, other relevant minerals such as magnesium were going relatively unremarked on. They suggest that parents in particular make sure their children get plenty of magnesium for healthy bone growth – and would like to see more awareness about the role magnesium plays in bone health increase in general.
