What does a epiphyseal line indicate?
What does a epiphyseal line indicate?
When the chondrocytes in the epiphyseal plate cease their proliferation and bone replaces the cartilage, longitudinal growth stops. All that remains of the epiphyseal plate is the epiphyseal line. It indicates that the epiphyseal growth has ended.
What is the purpose of the epiphyseal line cartilage?
Epiphyseal cartilage is hyaline cartilage tissue with a gelatinous texture, and it is responsible for the longitudinal growth of the long bones in birds and mammals. It is located between the epiphysis and the diaphysis.
What happens at the epiphyseal line?
When bone growth is complete, the epiphyseal cartilage is replaced with bone, which joins it to the diaphysis. Fractures of the epiphyseal plates in children can lead to slow bone growth or limb shortening. The coordinated activity of these bone cells allows bone to grow, repair itself, and change shape.
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 another name for epiphyseal?
growth plate
The growth plate, also known as the epiphyseal plate or physis, is the area of growing tissue near the end of the long bones in children and adolescents.
What is the common name for epiphysis?
In this page you can discover 10 synonyms, antonyms, idiomatic expressions, and related words for epiphysis, like: pineal-gland, pineal body, epiphysis cerebri, trochlea, clavicle, metaphysis, diaphysis, popliteal, fibula and condyle.
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. The epiphysis is completely or mostly cartilaginous in infants.
What is the function of epiphysis?
Epiphysis Definition – Epiphysis is the rounded end of a long bone, its primary function is to connect adjacent bones to form joints.
What epiphysis means?
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. The epiphysis is made of spongy cancellous bone covered by a thin layer of compact bone.
When is the growth plate replaced by an epiphyseal line?
The plate is only found in children and adolescents; in adults, who have stopped growing, the plate is replaced by an epiphyseal line. This replacement is known as epiphyseal closure or growth plate fusion.
Which is the correct terminology for the epiphysial plate?
This article uses anatomical terminology. The epiphyseal plate (or epiphysial plate, physis, or growth plate) is a hyaline cartilage plate in the metaphysis at each end of a long bone.
When does epiphyseal fusion occur in a bone?
Each bone has a predictable age range when long bone fusion occurs; in fact, different ends of the bone each have their own individual range. The table below gives examples of five different long bones and the expected age where epiphyseal fusion occurs. Until that point, the end of the bone is a distinct and separate piece from the shaft.
When does metaphysis and epiphysis fuse together?
If growth is still ongoing, more cartilage is laid down on that bone as the growth plate moves farther away from the center of the shaft, and the process repeats. When maturity is finally reached, growth stops and the epiphysis and metaphysis permanently fuse together. The x-ray below shows a normal adult knee.
What is the definition of epiphyseal line?
Medical Definition of epiphyseal line. : the line marking the site of an epiphyseal plate that has has stopped growing and become ossified.
Where is the epiphyseal line located?
Epiphyseal Line. The structure indicated is the epiphyseal line. The epiphyseal plate is a plate of hyaline cartilage found in children and adolescents, located in the metaphysis at the ends of each long bone.
What is the purpose of the epiphyseal plate?
The role of the epiphyseal plate is to turn new cartilage into bone. Because of this, all of the long bones have at least two different epiphyseal plates which typically rest at the ends of the bone. Over time, as a child grows, the cartilage is turned into hard bone.
