What does metaphysis mean?
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 the function of the metaphysis?
function in bone structure This region (metaphysis) functions to transfer loads from weight-bearing joint surfaces to the diaphysis. Finally, at the end of a long bone is a region known as an epiphysis, which exhibits a cancellous internal structure and comprises the bony substructure of the joint surface.
What type of bone is the metaphysis?
The metaphysis is the neck portion of a long bone between the epiphysis and the diaphysis. It contains the growth plate, the part of the bone that grows during childhood, and as it grows it ossifies near the diaphysis and the epiphyses….

Is the metaphysis the shaft?
As you can see in Figure 5.1, the shaft of a long bone is called the diaphysis. The central, fat-storing marrow cavity is found inside the diaphysis. At each end of the bone, at the site of the synovial joint, is an area called epiphysis. At the juncture between the two is an area called the metaphysis.
What is a marrow cavity?
The medullary cavity (medulla, innermost part) is the central cavity of bone shafts where red bone marrow and/or yellow bone marrow (adipose tissue) is stored; hence, the medullary cavity is also known as the marrow cavity.
Do adults have a metaphysis?
In the adult, only the metaphysis and diaphysis are present (Figure 1). Figure 1: Anatomical differences between adult and child bone.
What is a shaft bone?
Anatomical 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.
What is yellow marrow?
There are two types of bone marrow: red and yellow. Red marrow contains blood stem cells that can become red blood cells, white blood cells, or platelets. Yellow marrow is made mostly of fat.
What is intramedullary canal?
Intramedullary is a medical term meaning the inside of a bone. Examples include intramedullary rods used to treat bone fractures in orthopedic surgery and intramedullary tumors occurring in some forms of cancer or benign tumors such as an enchondroma.
Is metaphysis the same as physeal?
Physeal injuries are a the term physis is used rather than “growth plate.” the metaphyses. During growth, the epiphyseal and metaphyseal regions contributor to longitudinal growth of the bone. The larger long bones
What are the basics of metaphysics?
Metaphysics: The Basics is a concise and engaging introduction to the philosophical study of some of the most important and foundational aspects of the world in which we live. Concerned with questions about existence, time, identity, change, and other basic elements of our common-sense and scientific ways of thinking about the world, metaphysics has long fascinated people.
What is the beginning of osteoporosis?
Celiac disease
The metaphysis is the wider portion of a long bone adjacent to the epiphyseal plate. This is the part of the bone that grows during childhood; as it grows, it ossifies near the diaphysis and the epiphyses. At roughly 18 to 25 years of age, the metaphysis stops growing altogether and completely ossifies into solid bone.
