Is metaphysis the same as epiphyseal plate?
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.

What is the difference between metaphysis and epiphysis?
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).
Is the metaphysis the growth plate?
The growth plate, or physis, is the translucent, cartilaginous disc separating the epiphysis from the metaphysis and is responsible for longitudinal growth of long bones.
Is the growth plate in the epiphysis or metaphysis?
Growth plates, also called physes or epiphyseal plates, are discs of cartilage present in growing children. They are located between the middle and the end of the long bones, such as the bones of the arms and legs. Most long bones have one growth plate at each end.
What is a epiphyseal 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.
What is the metaphysis of a bone?
The metaphysis is the region where the epiphysis joins the diaphysis; in a growing bone this corresponds to the calcified layer of the epiphyseal plate together with the interdigitating bone (see Figure 4.19). The interface between the hypertrophic and calcified layers is sometimes referred to as the tidemark.
What is the epiphyseal plate?
The epiphyseal growth plate consists of a layer of cartilage present only during the growth period and vanishes soon after puberty in long bones. It is divided to three well-defined zones, from epiphyses; resting, proliferative, and hypertrophic zones.
What type of bone is the metaphysis?
long bones
The metaphysis is the trumpet-shaped end of long bones. It has a thinner cortical area and increased trabecular bone and is wider than the corresponding diaphyseal part of the bone.
Does bone growth occur in the metaphysis?
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 metaphysis?
The metaphysis is the region where the epiphysis joins the diaphysis; in a growing bone this corresponds to the calcified layer of the epiphyseal plate together with the interdigitating bone (see Figure 4.19).
Which bones have epiphyseal plates?
Growth Plates
- the femur (thighbone)
- the lower legs (tibia and fibula)
- the forearm (radius and ulna)
- the bones in the hands and feet.
What is the purpose 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 in the metaphysis?
At what age do epiphyseal 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 5 zones of the epiphyseal plate?
Terms in this set (5)
- Resting Zone. Area of cartilage on epiphyseal side of epiphyseal plate that is relatively inactive.
- Proliferation (growth) zone. Area of cartilage on diaphysis side of epiphyseal plate that is rapidly dividing.
- Hypertrophic zone.
- Calcification zone.
- Ossification zone.
What is a metaphysis?
Can exercise damage growth plates?
You may have heard rumors that weight training can stunt growth. The concern is that weight training can injure the areas of the bone that grow (the growth plates) and limit stature. There is no evidence that high-impact sports like gymnastics, soccer, football, and basketball harm growth plates.
What happens if the epiphyseal plate is damaged?
Growth plate fractures often need immediate treatment because they can affect how the bone will grow. An improperly treated growth plate fracture could result in a fractured bone ending up more crooked or shorter than its opposite limb. With proper treatment, most growth plate fractures heal without complications.
What age does the 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.
How do you stimulate growth plates?
Is there anything you can to do influence your growth or height?
- regular stretching.
- strengthening your core.
- sitting with good posture regularly.
- exercising regularly.
- avoiding slouching.
At what age growth plates close?
How do you know if your growth plates are damaged?
What Are the Signs & Symptoms of a Growth Plate Fracture? A child with a growth plate fracture can have pain, swelling, and trouble moving and using the injured body part. Sometimes there is a deformity — this means that the body part looks crooked or different than it did before the injury.
Does height come from Mom or Dad?
#3 Height. At least 700 genetic variations are responsible for determining height, coming from both mom and dad’s genes. But there is evidence to suggest that each parent’s “height gene” functions a bit differently. Dad’s genes play a significant role in promoting growth.
Does height come from mother or father?
As a general rule of thumb, your height can be predicted based on how tall your parents are. If they are tall or short, then your own height is said to end up somewhere based on the average heights between your two parents. Genes aren’t the sole predictor of a person’s height.
How do you tell if growth plates are still open?
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.
