What is the difference between epiphyseal plate and epiphyseal line? What is the difference between an epiphyseal plate and an epiphyseal line? The Epiphyseal plate contains cartilage used for producing bone. The Epiphyseal line is formed after the epiphyseal plate has stopped producing bone). … The Periosteum is the covering of a bone.
Why is the epiphyseal line important?
In adults, the epiphyseal plate is replaced with the epiphyseal line and marks the point of union were the epiphysis meets the diaphysis. The epiphyseal plates permit growth and lengthening of the bone, as the cartilage reproduces and ossifies.
What is another name for the 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.
What does an epiphyseal line indicate?
What does the presence of an epiphyseal line indicate? It indicates that the epiphyseal growth has ended.
Is epiphysis present in adults?
The long bone in a child is divided into four regions: the diaphysis (shaft or primary ossification centre), metaphysis (where the bone flares), physis (or growth plate) and the epiphysis (secondary ossification centre). In the adult, only the metaphysis and diaphysis are present (Figure 1).
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 are the 5 zones of the epiphyseal plate?
Study each of the five zones of the epiphyseal plate:
- Zone of Reserve Cartilage (RC). …
- Zone of Proliferating Cartilage (PC). …
- Zone of Hypertrophic Cartilage (HC). …
- Zone of Calcified Cartilage (CC). …
- Zone of Ossification (Resorption)(OSS).
What is the difference between metaphysis and epiphyseal plate?
Lengthening of Long Bones. The epiphyseal plate is the area of growth in a long bone. … The metaphysis is the wide portion of a long bone between the epiphysis and the narrow diaphysis.
How do you know if epiphyseal plates are closed?
On an x-ray, growth plates look like dark lines at the ends of the bones. At the end of growth, when the cartilage completely hardens into bone, the dark line will no longer be visible on an x-ray. At that point, growth plates are considered closed.
Does a person with epiphyseal lines growing taller?
Bones increase in length by the process of ossification. 3. A person with epiphyseal lines is not growing taller.
What’s 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. The diaphysis, or shaft, of the long bone, is another prominent feature.
What is epiphysis and its types?
There are four types of 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). … Traction epiphysis: The regions of the long bone which are non-articular, i.e. not involved in joint formation.
How many epiphysis are there?
Structure. There are four types of 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).
How the epiphyseal plate grows?
Bones grow in length at the epiphyseal plate by a process that is similar to endochondral ossification. The cartilage in the region of the epiphyseal plate next to the epiphysis continues to grow by mitosis. The chondrocytes, in the region next to the diaphysis, age and degenerate.
What is the zone of proliferating cartilage?
Zone of reserve (« resting ») cartilage (unmodified hyaline). 2. Zone of proliferating cartilage . . . clusters (cell nests) of chondrocytes undergo successive mitotic divisions to form columns of cells separated by deeply staining matrix.
What are the 4 zones of the epiphyseal plate?
Terms in this set (4)
- Proliferation Zone. Zone 1. Cartilage cells undergo mitosis.
- Hypertrophic Zone. Zone 2. Older cartilage cells enlarge.
- Calcification Zone. Zone 3. Matrix becomes calcified; cartilage cells die; matrix begins deteriorating.
- Ossification Zone. Zone 4. New bone formation is occurring.
What is the epiphyseal 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.
At what age do epiphyseal plates close?
When Do Growth Plates Close? Growth plates usually close near the end of puberty. For girls, this usually is when they’re 13–15; for boys, it’s when they’re 15–17.
What are the four layers of the epiphyseal plate?
Terms in this set (4)
- Layer closest to epiphysis; where cartilage remains. Resting zone.
- Chondrocytes producing new cartilage cells. Proliferating zone.
- Cartilage cells are dying off. Degenerating zone.
- Zone where bone is forming. Ossification zone.
Can I still grow taller at 30?
No, an adult cannot increase their height after the growth plates close. However, there are plenty of ways a person can improve their posture to look taller. Also, a person can take preventative measures against height loss as they age.

Where is the epiphyseal line?
An epiphyseal line is an epiphyseal plate that has become ossified. The process of it forming from an epiphyseal plate is named epiphyseal closure. In adult humans, it marks the point of fusion between the epiphysis and the diaphysis.
Can you grow taller after growth plates close?
