Question

Quizplus · Accepted Answer

Interstitial growth of the epiphyseal plates is the process that contributes to lengthwise long bone growth during infancy and youth. The epiphyseal plate is a layer of hyaline cartilage found in between the epiphysis and metaphysis of growing long bones. This cartilage layer allows for differentiation and proliferation of chondrocytes that secrete new cartilage matrix, which eventually calcify and form new bone tissue, leading to long bone growth.
