Diaphízisének

Diaphízisének is a Hungarian term referring to the diaphysis, which is the shaft or central part of a long bone. In anatomy, long bones are characterized by having a diaphysis and two epiphyses. The diaphysis is primarily composed of compact bone tissue, which provides strength and rigidity to the bone. It is hollow and contains the medullary cavity, also known as the bone marrow cavity. This cavity is filled with bone marrow, which can be red marrow responsible for hematopoiesis (blood cell production) in children and some adults, or yellow marrow which is primarily fat storage in adults. The diaphysis is formed during the process of endochondral ossification, where cartilage is replaced by bone. It grows in length through the activity of the epiphyseal plate, located between the diaphysis and the epiphysis, and in diameter through appositional growth on the outer surface of the periosteum. The diaphysis plays a crucial role in supporting the body's weight and facilitating movement. Fractures to the diaphysis are common and can range in severity.
