What is the function of the diaphysis?
The diaphysis plays an essential role in the structural functionality, the transport of oxygen and immune support, and mineral and fat storage. The medullary cavity, housed within the diaphysis, is where blood products, including red blood cells, white blood cells, and platelets, are formed.
What is diaphysis in skeletal system?
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 quizlet?
Diaphysis (definition) the shaft of a long bone. Periosteum (definition) A fibrous, vascular membrane that covers the bone.
What is a diaphysis in biology?

Which of the following are functions of osteocytes?
The potential functions of osteocytes include: to respond to mechanical strain and to send signals of bone formation or bone resorption to the bone surface, to modify their microenvironment, and to regulate both local and systemic mineral homeostasis.
Which bone contains a diaphysis?
the long bone
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 function of epiphyseal plate?
The epiphyseal growth plate is the main site of longitudinal growth of the long bones. At this site, cartilage is formed by the proliferation and hypertrophy of cells and synthesis of the typical extracellular matrix.
What contains diaphysis?
The shaft in the middle of the bone is called the diaphysis. 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.
What is the function of canaliculi?
Small channels (canaliculi) radiate from the lacunae to the osteonic (haversian) canal to provide passageways through the hard matrix. In compact bone, the haversian systems are packed tightly together to form what appears to be a solid mass.
Do all bones have diaphysis?
Long bones of the leg include the femur, tibia, fibula, metatarsals, and phalanges. The clavicles (collar bones) are also long bones. Long bones provide the leverage we need for moving our bodies and for manipulating our environment. All long bones have two main parts: diaphysis and epiphysis.
What is the function of the diaphysis in bones?
The diaphysis It 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. Not all bones have diaphyses, only long bones.
What is the synonym of diaphysis?
Synonym (s): diaphysis [TA] . The shaft of a long bone. Distinguish from EPIPHYSIS, the growth zone at the ends of a long bone. the shaft of a long bone.
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 is an epiphysis in a long bone?
As we know, the long bones are composed of a body or diaphysis and of extremities or articular heads, the epiphyses. In compound separations of epiphysis, the end of the diaphysis may be pushed through the skin. Manual of Surgery Volume Second: Extremities–Head–Neck.
