Where 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.
Where would you find an epiphyseal plate and what is its function?
The epiphyseal plate is the area of growth in a long bone. It is a layer of hyaline cartilage where ossification occurs in immature bones. On the epiphyseal side of the epiphyseal plate, cartilage is formed. On the diaphyseal side, cartilage is ossified, allowing the diaphysis to grow in length.
Where are the growth plates located?
Growth plates are located near the ends of your child’s bones. If a fracture goes through a growth plate, it can result in a shorter or crooked limb.
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.
Is the epiphyseal plate in the metaphysis?
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.
Which of the following regions of the epiphyseal plate is nearest the epiphysis?
The reserve zone is the region closest to the epiphyseal end of the plate and contains small chondrocytes within the matrix.
What is the area where marrow is located quizlet?
In children, red bone marrow is found in the medullary cavity of the long bones. In adults, it is primarily found in the flat bones, such as the pelvic girdle or sternum. The red bone marrow contains hematopoietic cells, which are responsible for generating red blood cells. You just studied 3 terms!
Where is the growth plate in the humerus?
The growth plate is made up of cartilage cells, which are softer and more vulnerable to injury than mature bones. There is a growth plate at the part of the humerus closest to the shoulder.
Where is the growth plate in your hip?
Kids and teens also have a growth plate at the top of the thighbone (femur), just under the “ball” portion of the joint. This is called the physis, and it’s made out of cartilage, which is weaker than bone.
What type of joint is the epiphyseal plate?
cartilaginous joint
Synchondrosis. A synchondrosis (“joined by cartilage”) is a cartilaginous joint where bones are joined together by hyaline cartilage, or where bone is united to hyaline cartilage. A synchondrosis may be temporary or permanent. A temporary synchondrosis is the epiphyseal plate (growth plate) of a growing long bone.
Which blood vessels supply the epiphyseal plates?
The epiphyseal arteries supply blood to the epiphysis via multiple branches that arborize into the growth plate, providing vascularization into the proliferative zone to a depth of up to 10 cells. No vessels penetrate beyond the proliferative zone, making the hypertrophic zone avascular.
Where within the epiphyseal plate are the dividing cartilage cells located?
Near the outer end of each epiphyseal plate is the active zone dividing the cartilage cells.
