Detailed explanation-1: -The diaphysis is the tubular shaft that runs between the proximal and distal ends of the bone. The hollow region in the diaphysis is called the medullary cavity, which is filled with yellow marrow. The walls of the diaphysis are composed of dense and hard compact bone.
Detailed explanation-2: -The diaphysis 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).
Detailed explanation-3: -The diaphysis is the shaft portion of a long bone with cortical tissue. It has bone marrow and adipose tissue.
Detailed explanation-4: -The diaphysis, or central shaft, contains bone marrow in a marrow cavity. The rounded ends, the epiphyses, are covered with articular cartilage and are filled with red bone marrow, which produces blood cells (Figure 19.17). Most of the limb bones are long bones-for example, the femur, tibia, ulna, and radius.
