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 …

Jan 21, 2025 · 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 …

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.

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.

Feb 27, 2025 · 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 …

Feb 24, 2023 · 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 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.

Jul 5, 2024 · The diaphyses (singular: diaphysis), sometimes colloquially called the shafts, are the main portions of a long bone (a bone that is longer than it is wide) and provide most of their length. The diaphysis has a tubular composition with a hard outer section of hard cortical bone and a central portion with cancellous bone and bone marrow cavity .

…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).
