Which of the following is the primary mechanism by which long bones increase in length?
Show answer and explanation
Correct answer: Interstitial growth at the epiphyseal plate
Long bones lengthen through endochondral ossification, which relies on the interstitial growth of cartilage within the epiphyseal plate. As new cartilage is formed and subsequently calcified and replaced by bone, the diaphysis is pushed away from the epiphysis.
