Bone growth in length occurs by interstitial growth of the cartilage of the epiphyseal plate, whereas bone growth in width is accomplished by appositional growth occurring deep to the periosteum. Osteoblasts derived from osteoprogenitor cells of the periosteum secrete bone matrix on the bone surface,...
Growth in long bones occurs at the epiphyseal growth plate (EGP) next to the metaphysis in a process called endochondral ossification. Chondrocyte proliferation, hypertrophy, and apoptosis in the EGP depend on several factors such as genetics, nutrition, environment, and hormones, which influence endo...
Understand the bone growth process. Discover more about the hormones regulating bone growth, the bone formation process at various stages, and bone growth disorders. Related to this Question Explain the process of bone growth both in length (interstitial) and thickness (appositional). ...
Bone development is the formation and growth of bones. New bone is formed by the action of specialised cells called osteoblasts and osteoclasts, either by directly laying down bone tissue into connective tissue or forming it from cartilage, such as during growth in length of long bones. ...

Long bones are those such as the femur, which can grow in width (through appositional growth), and length (through interstitial growth). Answer and Explanation:1 Lengthening of long bones in humans occurs in an area of the bone called the epiphyseal plate. Thi...
growth in length of long bones epiphyseal plate consists of five zones: (RPHCO) chondroblasts divide less often, replaced by bone, occurs when epiphysis and diaphysis fuse, 18/21 growth in length of long bones: - near end of adolescence, -epiphyseal plate thins, epiphyseal plate closure -...
walls break down between lacunae in columns, spaces invaded by capillaries and osteoprogenitor cells, new bone matrix deposited on the calcified cartilage matrix appositional growth bone growth in width, occurs in periosteum, bone matrix deposited within layers parallel to surface, osteoclasts resorb bon...
Unlike bone modeling, bone remodeling occurs at a specific site and in a consecutive order—activation, resorption, and formation (ARF). During the processes of bone remodeling, the osteoclasts and osteoblasts work sequentially to resorb and deposit new bone in response to normal turnover, ...
Growth factors In this review the term “growth factor” refers to soluble, secreted signaling polypeptides or proteins, which can be synthesized by a wide variety of cells and play an important role in the regulation of cell proliferation, migration, differentiation, and ECM synthesis.58Growth fac...
