Examples of diaphysis in the following topics:

  • Growth of Bone

    • On the diaphyseal side, cartilage is ossified, allowing the diaphysis to grow in length.
    • The metaphysis is the wide portion of a long bone between the epiphysis and the narrow diaphysis.
    • Capillaries and osteoblasts from the diaphysis penetrate this zone.
    • Thus, the zone of calcified matrix connects the epiphyseal plate to the diaphysis.
    • A bone grows in length when osseous tissue is added to the diaphysis.
  • Bone Development

    • In long bones, chondrocytes form a template of the hyaline cartilage diaphysis.
    • This calcification prevents diffusion of nutrients into the matrix, resulting in chondrocytes dying and the opening up of cavities in the diaphysis cartilage.
    • Osteoclasts then break down some of the spongy bone to create a marrow, or medullary cavity, in the center of the diaphysis.
    • Until adolescence, hyaline cartilage persists at the epiphyseal plate (growth plate), which is the region between the diaphysis and epiphysis that is responsible for the lengthwise growth of long bones.
  • Bone

    • The weight of the body pushes it down near the joint, but the vertical diaphysis of the femur pushes it up at the other end.
  • Connective Tissues: Bone, Adipose, and Blood

    • Compact bone is found in the shaft (or diaphysis) of a long bone and the surface of the flat bones, while spongy bone is found in the end (or epiphysis) of a long bone.
