Vascular of or relating to or having vessels that conduct and circulate fluids. Other causes in bone include hyperbaric exposure diving excessive intake of corticosteroids or alcohol and some diseases. Commonly occurs after fracture of the femoral neck leading to death of the femoral head.

It may also be referred to as osteonecrosis. If not stopped this process eventually causes the bone to collapse. Without a blood supply.

Cells fit together and form sheets the apical surface is the free surface of the tissue the lower surface of the epithelium rests on a basement membrane avascular.
