WebLow levels of collagen make for brittle bones; low levels of hydroxyapatite result in bones that are weak and easily bendable. During bone deposition, osteoblasts produce collagen fibers, the organic portion of the bone matrix. This … WebOsteoblasts are bone cells that are responsible for bone formation. Osteoblasts synthesize and secrete the organic part and inorganic part of the extracellular matrix of bone tissue, …
WebThe collagen fibers of the osteoid make the overall bone matrix stronger by allowing it to resist bending and twisting forces. True or False. True (The organic matrix, or osteoid, … WebJan 5, 2013 · The osteoblasts move over the matrix of a bone and deposit a protein mixture called osteoid. The osteoid contains a protein called collagen as its major component. Then the osteoblasts deposit minerals—including calcium—into the osteoid to make bone. The new material fills in the cavity formed by osteoclasts.
WebOsteoblasts are rich in the enzyme alkaline phosphatase, which plays a major role in the formation of the mineral deposits in the matrix. The collagen fibers are synthesized and secreted by the osteoblasts. The matrix closest to the osteoblasts is not yet calcified and is known as osteoid or prebone ... WebUnder such conditions, mesenchymal osteoblasts secret collagen fibers rapidly and randomly in all directions (Shapiro, 1988, 2008). However, most bone in a healthy adult which is formed as a result of the remodeling …
