Bone growth during adolescence occurs at growth plates located at the ends of each long bone. Growth plates contain cartilage cells that constantly divide and move inward to the middle of the bone, calcifying and solidifying in the process. This ultimately lengthens the bone, and by adulthood, the growth plates also solidify into a thin scar that stops growth. Seen here are multiplying cartilage cells moving inward during growth.
