What is the medical term meaning growth zone of a long bone?
epiphyseal plate
What part of the bone such as the femur enables the bone to get longer?
The part of the bone that enables it to get longer is called the epiphyseal plate, or growth plate. This cartilage zone is located at the ends of long bones, like the femur, and is where new bone tissue is formed during growth. As a person matures, the growth plates gradually ossify and turn into solid bone, eventually stopping further lengthening of the bone.
What is the Physiological zone of bone growth?
whena bone grows by osteoblasts
How does the appearance of the chondrocytes in the transformation zone differ from those in the growth zone in bone?
Chondrocytes in the transformation zone of bone are larger and arranged in columns, while in the growth zone they are smaller and arranged randomly. Additionally, chondrocytes in the transformation zone undergo hypertrophy before turning into bone, whereas those in the growth zone are actively dividing and producing new cartilage.
What is the structure of an epiphyseal plate?
The epiphyseal disk is the growth plate in long bones that is found between the two epiphyses and the diaphysis. This is a space that remains as long as a person is growing. When growth is completed, the epiphyses and the diaphysis meet and fuse forming a line.
Chondrocytes multiply in this zone of the metaphysis?
Chondrocytes multiply in the proliferation zone of the metaphysis. This zone is responsible for longitudinal bone growth as chondrocytes divide and contribute to the formation of new cartilage.
What are the function of the resting cartilage zone?
The resting cartilage zone, also known as the zone of resting cartilage, is a layer of hyaline cartilage located at the epiphyseal plate in growing long bones. Its primary function is to serve as a reserve of chondrocytes, which can proliferate and differentiate into the next zones of the growth plate, contributing to endochondral ossification. This zone helps maintain the structural integrity of the growth plate while allowing for linear bone growth. Additionally, it plays a role in the overall regulation of skeletal development and growth.
Where is the area of growth in the length of a long bone?
Epiphysial cartilage
What marginal zone of the epiphyseal plate where in children and adolescents bone can be seen replacing the hyaline cartilage?
The region you are referring to is called the ossification or metaphysis zone of the epiphyseal plate. In this area, new bone tissue is formed as osteoblasts replace the hyaline cartilage. This process helps in the longitudinal growth of bones during childhood and adolescence.
Does zone have a long o sound?
Yes. The O is a long "oh" provided by the silent E. It rhymes with bone and phone.
At the epiphyseal plate, which zone is characterized by older cartilage cells that are enlarging?
The zone characterized by older cartilage cells that are enlarging at the epiphyseal plate is the hypertrophic zone. In this zone, chondrocytes cease dividing and start to enlarge, contributing to longitudinal bone growth.
Where within the epiphyseal plate is the dividing cartilage cells located?
The dividing cartilage cells are located in the zone of proliferation within the epiphyseal plate. This zone is where chondrocytes actively divide and contribute to bone growth.
