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 outer walls of the diaphysis (cortex, cortical bone) are composed of dense and hard compact bone, a form of osseous tissue.

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 marrow cavity which contains red or yellow marrow. In diaphysis, primary ossification occurs.

2020年11月13日 · The femur is the only bone in the thigh and the longest bone in the body. It acts as the site of origin and attachment of many muscles and ligaments, and can be divided into three parts; proximal, shaft and distal.

2023年9月11日 · The shaft is relatively wide at the proximal end but becomes progressively narrow toward the middle. It is bowed anteriorly, which contributes to the weight bearing …

2023年10月30日 · A shaft, or diaphysis, connects the two ends known as the epiphyses (plural for epiphysis). The marrow cavity is enclosed by the diaphysis which is thick, compact bone. The epiphysis is mainly spongy bone and is covered by a thin layer of compact bone; the articular ends participate in the joints.

A long bone can be divided into two parts – (1) the central shaft or diaphysis and (2) the epiphyses (singular: epiphysis), the bulky ends on both sides. There is a narrow section called (3) metaphysis between the diaphysis and epiphysis.

A long bone has two parts: the diaphysis and the epiphysis. 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.

The diaphysis is the narrow, tubular shaft that runs between the two bulbous ends of the bone. These bulbous ends are the epiphyses (proximal and distal) and metaphyses (proximal and distal). Within the diaphysis is a hollow region called the medullary cavity, which is filled with yellow marrow (in adults).

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.

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 …
