The diaphysis (pl.: diaphyses) is the main or midsection (shaft) of a long bone. It is made up of cortical bone and usually contains bone marrow and adipose tissue (fat). It is a middle tubular part composed of compact bone which surrounds a central marrow cavity which contains red or yellow marrow. In diaphysis, primary ossification occurs.
Primary endochondral ossification begins with the formation of a chondrocyte template. Afterwards, chondrocytes undergo hypertrophy beginning from the mid-diaphysis, eventually extending to the epiphyseal poles, vasculature invades the forming bone transporting mesenchymal stromal cells and hypertrophic cells undergo apoptosis. Mesenchymal ...

However, it serves as an indicator of the boundary between the epiphysis and diaphysis. [4] References This page was last edited on 30 July 2024, at ...
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 ...
