A long bone has two main regions: the diaphysis and the epiphysis (Figure 6.3.1). The diaphysis is the hollow, tubular shaft that runs between the proximal and distal ends of the bone. Inside the diaphysis is the medullary cavity, which is filled with yellow bone marrow in an adult.

The diaphysis (pl.: diaphyses) 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). It is a middle tubular part composed of compact bone which surrounds a central …

2025年1月21日 · The diaphysis is the central, elongated shaft of a long bone. It is a crucial component of the bone's structure, providing support and enabling movement.[3] The diaphysis is characterized by its cylindrical shape, which allows it to …

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 .

1. Diaphysis. The central tubular shaft connects the two ends of the bone. Its walls are composed of dense and hard compact bone, forming an internal hollow region called the medullary cavity (as shown in the cross-section image above).
