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 shaft portion of a long bone with cortical tissue. It has bone marrow and adipose tissue.
Detailed explanation-3: -The long bone in a child is divided into four regions: the diaphysis (shaft or primary ossification centre), metaphysis (where the bone flares), physis (or growth plate) and the epiphysis (secondary ossification centre). In the adult, only the metaphysis and diaphysis are present (Figure 1).
