Osteoclasts do not become osteocytes. They are strongly acid-phosphatase-positive. An osteoblast is a cell that is generating new bone matrix i.e., a bone forming cell.It does this by creating the organic component in bone, namely collagen.As osteoblasts move along the bone matrix, they get stuck in the tissue and turn into osteocyctes.This creates new bone growth and repair.

There are two distinct features of an osteoclast: a ruffled border and a sealing zone. part in direct contact with bone. Osteoclasts are cells that break down old bone cells to make way for osteoblasts to stimulate new bone growth. cells with a single nucleus that synthesize bone. 3,79,80 Accumulation of apoptotic osteocytes in certain areas of bone promotes preosteoclast recruitment, local osteoclast differentiation, and increased resorption. There are two distinct features of an osteoclast: a ruffled border and a sealing zone. Thus, between them, the three types of bone cells regulate the formation, sustenance, and decay of bones. Osteoclasts are derived from monocyte fusion and have from about 2 to 12 nuclei per cell. Organic= cells and proteins= 35%... 2. An osteoclast (from Ancient Greek ὀστέον (osteon), meaning 'bone', and κλαστός (clastos), meaning 'broken') is a type of bone cell that breaks down bone tissue. Learn vocabulary, terms, and more with flashcards, games, and other study tools. Osteocytes are ____ Mature bone cells that monitors and maintains the mineralized bone matrix. Hematopoietic stem cells (HSC) differentiate into all blood cell lineages (), including the mononuclear phagocyte system from which OC arise.Consistent with the conventional view that bone marrow niches are the primary sites of postnatal hematopoiesis (), medullary fractions from humans and animal models are excellent sources of OC precursors. They have 2-12 nuclei (typically 5) and are 150-200µm in diameter. Start studying A+P Winter Exam 1. Osteoclast definition, one of the large multinuclear cells in growing bone concerned with the absorption of osseous tissue, as in the formation of canals. Osteoblasts are a type of bone cells.
