When the epiphysis closes on a bone, the bone can no longer grow in length. The closure of the epiphysis marks the end of longitudinal bone growth, but the bone can still increase in thickness through a process called appositional growth.
The growth in bone length of a long bone occurs at the epiphyseal plate, also known as the growth plate. This area is found at the ends of long bones and is responsible for new bone formation during childhood and adolescence, ultimately determining the final length of the bone.
The process that increases bone length is called endochondral ossification, where cartilage is replaced by bone tissue, primarily occurring at the growth plates during childhood and adolescence. Bone diameter increases through a process called appositional growth, where new bone tissue is added to the outer surface of the bone by osteoblasts while osteoclasts resorb bone from the inner surface, maintaining overall bone strength and shape. Together, these processes enable bones to grow in both length and width throughout development.
The structure that remains after long bone growth has ended is called the epiphyseal line. This line forms when the epiphyseal plates, which are areas of cartilage responsible for lengthwise growth, ossify and close after puberty. The epiphyseal line signifies that the bone has reached its adult length and growth has ceased.
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.
When the bone increases in diameter, it is called appositional growth.
A thickening of bone occurs called appositional growth after the growth plate closes in late teens. If this type did not occur and the bone would just get thicker, we would weight about 200 pounds more than we do. The bone inside is removed by osteoclasts (bone breakers) while bone on the outside is laid down by osteoblasts (bone builders).
The process of bones increasing in width is called appositional growth. This occurs when new bone tissue is added to the existing bone surface, resulting in an increase in bone diameter.
The addition of new bone on top of existing bone to increase bone thickness is called appositional bone growth. This process involves the deposition of new bone tissue on the outer surface of existing bones.
Growth hormone is the hormone that stimulates bone and muscle growth. It is made in the pituitary gland. It is also known as somatotropin. Growth hormone is responsible for the increase in height in children and adolescents. It also increases bone density and muscle mass, and stimulates organ growth.
The epiphysis, commonly known as the growth plate, is the site of long-bone growth in a child or young adult. If a growing person has a fracture at this site, growth of bone length may be affected on that side, creating uneven limb length.
