What is diaphysis in bone?

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. 1 февр. 2016 г. differencebetween.comИзображение:differencebetween.comAnatomical terminology. The diaphysis 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. The diaphysis is a section of bone found only in long bones, such as the femur. A diaphysis is the long cylindrical section of a long bone and is made up of several distinct features. Like the outside of any bone, its superficial surface is covered by periosteum.All bones with diaphysis are known as long bones and in addition to the central part (diaphysis) they have two additional parts. These two parts are the epiphyses, located at the ends of the bone; and the metaphyses, which are located at the junction of the diaphysis and the epiphysis.



What is the diaphysis of the bone made of?

The diaphysis 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.

What is diaphysis and epiphysis in bone?

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. Furthermore, epiphysis is made up of spongy bone while diaphysis is made up of cortical bone.

What bones have diaphysis?

Diaphysis. The diaphysis is the shaft of the long bone, the main body. The diaphysis is a tube with a hollow center called the medullary cavity (or marrow cavity). The wall of the diaphysis is made up of compact bone, which is dense and very hard.

What is the structure and function of diaphysis?

The diaphysis contains the medulla of the bone, which houses bone marrow. The marrow is the primary tissue responsible for the production of erythrocytes, leukocytes, and platelets. The epiphysis is the terminal end of the long bone that is typically responsible for articulation.

What is bone epiphysis?

epiphysis, expanded end of the long bones in animals, which ossifies separately from the bone shaft but becomes fixed to the shaft when full growth is attained. The epiphysis is made of spongy cancellous bone covered by a thin layer of compact bone.

Where is the diaphysis of long bones located?

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.

What is metaphysis and diaphysis?

The central tubular region of the bone, called the diaphysis, flares outward near the end to form the metaphysis, which contains a largely cancellous, or spongy, interior. At the end of the bone is the epiphysis, which in young people is separated from the metaphysis by the physis, or growth plate.

What is the diaphysis of the long bone?

The diaphysis, or shaft, of the long bone, is another prominent feature. There is another part of the long bone between the epiphysis and the diaphysis, which we call metaphysics.

What is the difference between diaphysis and epiphysis?

The diaphysis is the long, tubelike shaft of long bones. It contains the medullary cavity, which is surrounded by a compact bone periosteum. The epiphysis is the end of a long bone and is spongy bone, containing red bone marrow, even in mature skeletons. What is the Diaphysis function?

What are the parts of the diaphysis?

Parts of the Diaphysis. Compared to the other parts that make up a long bone, the diaphysis is quite different. It has a hollow inside with an open space called the medullary cavity. The cavity is filled with yellow bone marrow, along with blood vessels that supply the living bone tissue.

Why don’t all bones have a diaphysis?

Not all bones have diaphysis, only long bones. The bony structures where it is located are located mainly in the extremities.
