Diaphysis

The diaphysis is the main or mid section (shaft) of a long bone. It is usually filled with Yellow Cartilage, which is made mostly of adipose (fat). This provides some protection to shaft when presure is applied. Yellow marrow also contains white blood cells, which is important in the body’s defense against disease.
