All physiological processes occur during the growth at the epiphyseal plate except: (A) Proliferation & hyperophy, (B) Calcification & ossification, (C) Vasculogenesis & erosion, (D) Replacement of red bone marrow with yellow marrow
Answer is D. O As the growth plate is ossified, it receives vascular buds & Vasculogenesis occurs, the new blood vessels helping the metaphyseal aery to anastomose with the epiphyseal aery. o Thus, metaphyseal aery are no more termed as end- aery in an adult o Erosion of bone keep happening by the osteoclast cells, which help in enlarging the marrow cavity
