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 …

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.

2024年9月25日 · A long bone has five zones: the diaphysis, two metaphyses, and two epiphyses. 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 …

1. the portion of a long bone between the ends or extremities, which is usually articular, and wider than the shaft; it consists of a tube of compact bone, enclosing the medullary cavity. Called also shaft. 2. the portion of a bone formed from a primary center of ossification. See illustration. Diaphysis. From Dorland's, 2000.

…region of the bone (diaphysis) is the most clearly tubular. At one or commonly both ends, the diaphysis flares outward and assumes a predominantly cancellous internal structure. This region (metaphysis) functions to transfer loads from weight-bearing joint surfaces to the diaphysis.

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).

2024年8月27日 · The diaphysis is the main or midsection (shaft) of a long bone and is primarily composed of compact bone, which provides strength and support. It contains the central medullary cavity filled with bone marrow, crucial for the production of blood cells.

2019年5月10日 · The main difference between epiphysis and diaphysis is that epiphysis is the rounded end of a long bone, at its joint with adjacent bone(s), whereas diaphysis is the main or midsection (shaft) of a long bone.

2021年4月13日 · The diaphysis is the central part of the long bones. It is responsible for supporting the weight of the body as columns and, at the same time, increasing the power of the muscles by working as a lever.
