WebThe medullary cavity (medulla- = marrow), or marrow cavity, is a hollow, cylindrical space within the diaphysis that contains fatty yellow bone marrow and numerous blood vessels in adults. This cavity minimizes the weight of the bone by reducing the dense bony material where it is least needed. WebThe endosteum is the delicate membrane lining the medullary cavity. The periosteum covers all portions of a bone's exterior except for where bones meet other bones as joints. In these areas, the bones are covered in articular cartilage to reduce friction between bones and the joint and serve as a shock absorber.
