What is diaphyseal side?
It is a layer of hyaline cartilage where ossification occurs in immature bones. On the epiphyseal side of the epiphyseal plate, cartilage is formed. On the diaphyseal side, cartilage is ossified, allowing the diaphysis to grow in length. The more mature cells are situated closer to the diaphyseal end of the plate.
What is diaphysis function?
-Main shaft of longbone; hollow, cylindrical shape, thick, compact bone. Function: Provide strong support without cumbersome weight. -Both ends of long bone made of cancellous bone filled with red marrow.
What are the 2 regions of a bone?
Gross Anatomy of Bones. A long bone has two main regions: the diaphysis and the epiphysis (Figure 6.3. 1).
Where is metaphysis located?
The metaphyses (singular: metaphysis) are the wide portions of long bones and the regions of the bone where growth occurs. Growth occurs at the section of the metaphysis that is adjacent to the growth plate (physis). The metaphysis is located between the diaphysis and epiphysis.
What is diaphyseal length?
The diaphyseal length of the femur is the variable with the least amount of expected error, averaging around 1.06 years (MSE) about the mean estimated age in the total sample with the sexes combined, and the least amount of real error, averaging around 0.88 years (MAR).
What is mid diaphysis?
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 the importance of Canaliculi?
The canaliculi connect to the adjacent cavities, instead of a central haversian canal, to receive their blood supply. It may appear that the trabeculae are arranged in a haphazard manner, but they are organized to provide maximum strength similar to braces that are used to support a building.
Where is the metaphysis and epiphysis?
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.
