GENERAL HISTOLOGY

Detailed explanation-1: -Bones grow in length at the epiphyseal plate by a process that is similar to endochondral ossification. The cartilage in the region of the epiphyseal plate next to the epiphysis continues to grow by mitosis. The chondrocytes, in the region next to the diaphysis, age and degenerate.

Detailed explanation-2: -By birth, several areas of cartilage remain in the skeleton, including growth plates at the ends of the long bones. This cartilage grows as the long bones grow, so the bones can keep increasing in length during childhood. Long bones ossify and get longer as they grow and develop.

Detailed explanation-3: -Long bones continue to lengthen (potentially throughout adolescence) through the addition of bone tissue at the epiphyseal plate. They also increase in width through appositional growth.

Detailed explanation-4: -Growth plates are the areas of new bone growth in children and teens. They’re made up of cartilage, a rubbery, flexible material (the nose, for instance, is made of cartilage). Most growth plates are near the ends of long bones. Long bones are bones that are longer than they are wide.
