What is epiphysis and its function?
Epiphysis Definition – Epiphysis is the rounded end of a long bone, its primary function is to connect adjacent bones to form joints. 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.
Where is epiphysis of the bone?
The wider section at each end of the bone is called the epiphysis (plural = epiphyses), which is filled internally with spongy bone, another type of osseous tissue. Red bone marrow fills the spaces between the spongy bone in some long bones. Each epiphysis meets the diaphysis at the metaphysis.
What does epiphyseal mean?
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. It is connected to the bone shaft by the epiphyseal cartilage, or growth plate, which aids in the growth of bone length and is eventually replaced by bone.
What is epiphysis plate?
A growth plate, also called an epiphyseal plate, is a section of cartilage located at the ends of the long bones of children and teenagers. It is here that new bone develops to add length as the child grows. Once a person has physically matured, usually in adolescence, these plates permanently close to form solid bone.
What is an example of an epiphysis?
Pressure epiphysis: The region of the long bone that forms the joint is a pressure epiphysis (e.g. the head of the femur, part of the hip joint complex). Examples of traction epiphyses are tubercles of the humerus (greater tubercle and lesser tubercle), and trochanters of the femur (greater and lesser).
What are characteristics of cartilage?
Definition: Cartilage is a tough, semitransparent, elastic, flexible connective tissue consisting of cartilage cells scattered through a glycoprotein material that is strengthened by collagen fibers.
Is the epiphysis the growth plate?
The growth plate, also known as the epiphyseal plate is a thin layer of cartilage that lies between the epiphyses and metaphyses, and is where the growth of long bones takes place.
Where is the proximal epiphysis?
long bone
The proximal epiphysis is the end of the long bone closest to the center of the body. The distal epiphysis is located at the end of the long bone that is farther away from the center of the body.
What are the 4 types of epiphysis?

What are the four types of epiphysis?
There are two types of epiphyses: (1) pressure epiphyses, which are found at the ends of long bones, and (2) traction epiphyses (apophyses), which are sites of origin or insertion of major muscles (e.g., the greater trochanter of the femur). The metaphysis is an area between the diaphysis and epiphysis.
