ANATOMY

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: -3 – Longitudinal Bone Growth: The epiphyseal plate is responsible for longitudinal bone growth. The proliferative zone is the next layer toward the diaphysis and contains stacks of slightly larger chondrocytes.

Detailed explanation-3: -Growth in height is driven by elongation of long bones due to chondrogenesis at the epiphyseal plates, also known as the growth plate. This process results from chondrocyte proliferation, hypertrophy, and extracellular matrix secretion.

Detailed explanation-4: -The growth plate is the area of tissue near the ends of long bones in children and teens that determines the future length and shape of the mature bone. Each long bone has at least two growth plates, one at each end, and they are longer than they are wide.

Detailed explanation-5: -Answer and Explanation: Bone growth in length is called interstitial growth, and bone growth in diameter (thickness) is called appositional growth. Interstitial growth mainly takes place on the hyaline cartilage at the epiphyseal plate that surrounds the ends of long bones.
