The epiphyseal plate is a hyaline cartilage plate in the metaphysis at each end of a long bone. The plate is found in children and adolescents; in adults, who have stopped growing, the plate is replaced by an epiphyseal line. Starting from the epiphyseal end of the plate and working inward toward the shaft, the first zone is a layer of resting cartilage (Fig. The resulting bone is a thick walled cylinder, that encloses a central bone marrow cavity. Epiphyseal plate zone (from epiphysis to diaphysis Description; Zone of reserve: Quiescent chondrocytes are found at the epiphyseal end: Zone of proliferation: Chondrocytes undergo rapid mitosis under influence of growth hormone: Zone of maturation and hypertrophy Explain how osteoblasts and osteoclasts regulate bone mass.

The epiphyseal plate (or epiphysial plate, physis, or growth plate) is a hyaline cartilage plate in the metaphysis at each end of a long bone.It is the part of a long bone where new bone growth takes place; that is, the whole bone is alive, with maintenance remodeling throughout its existing bone tissue, but the growth plate is the place where the long bone grows longer (adds length). Glucose 6-phosphate dehydrogenase activity in the zone of hypertrophic cartilage is stimulated in a log-linear fashion with increasing concentrations of parathyroid hormone over the range 0.001 - 1.0 pg/ml. XXII. Blood supply decreases from the reserve zone to the zone of degeneration. This preview shows page 8 - 10 out of 10 pages. Endochondral ossification is responsible for the initial bone development from cartilage in utero and infants and the longitudinal growth of long bones in the epiphyseal plate. On the epiphyseal side of the epiphyseal plate, cartilage is formed.On the diaphyseal side, cartilage is ossified, and the diaphysis grows in length. Osgood-Schlatter disease results from stress on the epiphyseal plate in the tibia, leading to excess bone growth and a painful lump at the knee. Epiphyseal plate zone of ossification contains both osteoblasts and osteocytes. Hereditary multiple exostoses is a genetic condition that is caused by growth irregularities of the epiphyseal plates of the long bones of the upper[10] and lower limbs.
