  2. Epiphyseal plate - Wikipedia

    en.wikipedia.org/wiki/Epiphyseal_plate

    The epiphyseal plate, 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).

  3. Metaphysis - Wikipedia

    en.wikipedia.org/wiki/Metaphysis

    It contains the growth plate, the part of the bone that grows during childhood, and as it grows it ossifies near the diaphysis and the epiphyses. The metaphysis contains a diverse population of cells including mesenchymal stem cells , which give rise to bone and fat cells, as well as hematopoietic stem cells which give rise to a variety of ...

  4. Ossification center - Wikipedia

    en.wikipedia.org/wiki/Ossification_center

    A primary ossification center is the first area of a bone to start ossifying. It usually appears during prenatal development in the central part of each developing bone. In long bones the primary centers occur in the diaphysis/shaft and in irregular bones the primary centers occur usually in the body of the bone. Most bones have only one ...

  5. Epiphysis - Wikipedia

    en.wikipedia.org/wiki/Epiphysis

    However, these transverse notches lack the typical cell columns found in normal growth plates, and do not contribute significantly to longitudinal bone growth. [12] Pseudo-epiphyses are found at the distal end of the first metacarpal bone in 80% of the normal population, and at the proximal end of the second metacarpal in 60%.

  6. Body shape - Wikipedia

    en.wikipedia.org/wiki/Body_shape

    Growth is usually completed between the ages of 13 and 18, at which time the epiphyseal plates of long bones close, allowing no further growth (see Human skeleton). [2] Many aspects of body shape vary with gender and the female body shape especially has a complicated cultural history.

  7. Endochondral ossification - Wikipedia

    en.wikipedia.org/wiki/Endochondral_ossification

    Epiphyseal growth plate: This transverse layer lies between the epiphysis and diaphysis. It’s composed of highly active chondrocytes and responsible for longitudinal bone growth. Consequently, the bone elongates at this growth plate until closure occurs at skeletal maturity.

  9. Ossification - Wikipedia

    en.wikipedia.org/wiki/Ossification

    In fracture healing, endochondral osteogenesis is the most commonly occurring process, for example in fractures of long bones treated by plaster of Paris, whereas fractures treated by open reduction and internal fixation with metal plates, screws, pins, rods and nails may heal by intramembranous osteogenesis.
