Why do peoples bones stop growing at the age of 20?
Bone growth is controlled by a variety of factors, including growth plates found at the ends of long bones. At around age 20, these growth plates ossify and turn into solid bone, which signals the end of longitudinal bone growth. After this point, bone remodeling and maintenance occur instead of growth.
Where is the growth plate of a long bone located?
The growth plate of a long bone is located at the end of the bone, near the joint. It is also known as the epiphyseal plate and is responsible for longitudinal growth during childhood and adolescence.
What structure is involved in long bone growth length?
Long bone growth in length occurs at the growth plate, also known as the epiphyseal plate. This is a cartilaginous area at the ends of long bones where new bone tissue is formed, leading to longitudinal bone growth.
Interstitial bone growth in long bones?
Interstitial bone growth in long bones occurs in the epiphyseal plate, or growth plate, located at the ends of long bones. Here, cartilage cells (chondrocytes) proliferate, differentiate, hypertrophy, and are replaced by bone tissue, leading to longitudinal bone growth. This process is crucial for growth and development in children and adolescents.
Which bone has long longitudinal axis and expanded ends?
The humerus is a bone in the upper arm that has a long longitudinal axis with expanded ends where it articulates with the scapula at the shoulder joint and the radius and ulna at the elbow joint.

What are growth lines?
A growth line is a dense transverse line observed in radiographs of long bones. These lines represent bone growth after cessation of longitudinal growth.
What is the site for longitudinal growth in a child?
The growth plate, also known as the epiphyseal plate, is the site for longitudinal growth in a child. It is a cartilage region at the ends of long bones where bone growth occurs, allowing bones to elongate during childhood and adolescence. Once growth is complete, the growth plates close and are replaced by solid bone.

The cartilage that is located at the end of long bones that closes when growth ceases is called the plate?
The cartilage at the end of long bones that closes when growth stops is known as the growth plate or epiphyseal plate. It is responsible for longitudinal bone growth during childhood and adolescence by ossifying to form solid bone.
Interstitial bone growth in long bones?
Interstitial bone growth in long bones occurs in the epiphyseal plate, or growth plate, located at the ends of long bones. Here, cartilage cells (chondrocytes) proliferate, differentiate, hypertrophy, and are replaced by bone tissue, leading to longitudinal bone growth.

The humerus is a bone in the upper arm that has a long longitudinal axis with expanded ends where it articulates with the scapula at the shoulder joint and the radius and ulna at the elbow joint.
What is the site of longitudinal growth in long bones?
The site of longitudinal growth in long bones occurs at the epiphyseal plate, also known as the growth plate. This plate is located between the epiphysis (the end part of the bone) and the diaphysis (the shaft) and consists of cartilage that gradually ossifies as the individual matures. As new cartilage is produced on the epiphyseal side, it pushes the diaphysis away, leading to an increase in bone length. Eventually, the epiphyseal plate closes, and further growth in length ceases.
What is the region of longitudinal growth in a child?
The region of longitudinal growth in a child is the epiphyseal plate, commonly known as the growth plate. This area is located at the ends of long bones and is responsible for bone lengthening during childhood and adolescence by the process of endochondral ossification. Once growth is complete, the growth plate closes and becomes a bony structure known as the epiphyseal line.
Which region of a growing bone contains a epiphyseal plate?
The epiphyseal plate, also known as the growth plate, is located in the region of the growing bone between the epiphysis and the diaphysis. It is found in the metaphysis of long bones and is responsible for the longitudinal growth of the bone during childhood and adolescence. As an individual matures, the epiphyseal plate eventually calcifies and is replaced by bone, leading to the cessation of growth in length.
Do growth plates lie between primary and secondary ossification centers?
Yes, growth plates (also known as epiphyseal plates) are located between the primary and secondary ossification centers in long bones. They allow for longitudinal bone growth by producing new cartilage cells that are eventually replaced by bone tissue. Once growth is complete, the growth plates ossify and the bone stops growing in length.
