What are bone cells?
Three different types of bone cells are present in bone tissue, each with its own essential function. They are responsible for cooperation, osteoblasts, osteoclasts and osteocytes for proper development and maintaining the skeleton and regulating the levels of minerals present in the bloodstream and throughout the body. Two related types of cells, lining and osteogenic cells are derived from osteoblasts, but have their own key functions for proper bone health.
osteoblasts
cells responsible for creating new bone tissue are osteoblasts. They are created in the marrow bones, which is a soft inner area containing stem cells, which also produce red and white blood cells. Osteoblasts that work together create a type of bone tissue called osteoid primarily from collagen, which is then mineralized. This means that calcium and other minerals come to the tissue, which increases bone cells.
Though osteoblasts are necessary in bone formation when the fetus develops in the womb and as the child grows, these bone cellThey continue to work after adulthood. The bones are constantly decomposed and build back, with about 4% of all bone surfaces have an active osteoblast activity at any time. This process is called rebuilding. The regular development of the new tissue allows bones to repair breaks or other injuries and change in response to the needs of the body. In addition, bones are exposed to stress through everyday use and develop small microfrapures that are constantly fixed.
As soon as the bone tissue has been unfolded and re -built, most osteoblast bone cells are pressed flat and no longer produces new tissue. They become lining cells and are used to protect the basic bone matrix. Cell lining is also crucial when regulating mineral levels, such as a dollar and phosphate, which allows these substances to go to and out of the bones as needed.
osteoclasts
Osteoclasts are large bone cells created in the marrow bones. Similarly in structure as white blood cells are responsibleé for breaking bone tissue, which is necessary for bone growth and healing. They begin as smaller cells called Osteoclast precursors, but are connected to osteoclasts with multiple cores when they find places into bones that need to be divided, a process called resorption.
Although the number of osteoclasts is relatively small, they are vital not only for the creation of a new bone, but also to help regulate minerals in the bloodstream. When these cells decompose bones, they release calcium and phosphate into the blood, where these minerals play an important role in many biochemical processes. Osteoclasts are also involved in the development of red blood cells in the bone marrow.
ALSO research suggests that osteoclasts have immune receptors and that there are close links between immune and skeletal systems. Exactly as these two interact, although studies on autoimmune diseases such as rheumatoid arthritis, show how the immune system can affect bone respior. Osteoclasts are also associated with other diseases; When they break the bones of the rycLook, before they can be rebuilt, for example osteoporosis is the result.
osteocytes
After the creation of a new bone tissue, osteoblasts remain that do not become lining cells, deep in the bone matrix and become osteocytes, cells with long branches over the bone tissue that form the net. Osteocytes act as a control center that direct mineral deposits and send osteoclasts to repair bone tissue damage as needed. They are also responsible for signaling the release of minerals such as calcium into the bloodstream to maintain good health.
Osteocytes are most communicated bone cells and can live for decades. Some are programmed to die naturally, but conditions such as osteoarthritis and osteoporosis are associated with elevated cell death levels. In other words, when a higher number of osteocytes die, the bones have become weaker.
precursors
Most bone cells are unable to split up and cannot be reproducedforge. Osteogenic cells are bone cells capable of creating new osteoblasts and osteoclasts. They are located in periosteum, which is tissue surrounding the bone and bone marrow. Injuries, such as a fracture, start the production of cells with osteogenic cells and create new osteoblasts and osteocytes to repair damage as quickly as possible.
