Which bone marrow type is found in the diaphysis and stores fat?

Explanation:
Long bones have distinct marrow compartments with different roles. The diaphysis—the shaft of the bone—houses the medullary cavity filled in adults by yellow bone marrow, which is rich in adipocytes and serves as a fat storage reserve. Red bone marrow, responsible for making blood cells, is located in the epiphyses and other cancellous regions where hematopoiesis occurs, and its activity is higher in children. Cartilage and tendons aren’t marrow tissue. So the substance stored in the diaphysis is fat stored in yellow marrow.
