Detailed explanation-1: -During appositional growth, osteoclasts resorb old bone that lines the medullary cavity, while osteoblasts, via intramembranous ossification, produce new bone tissue beneath the periosteum.
Detailed explanation-2: -Answer and Explanation: Bones grow in diameter due to bone formation (b) beneath the periosteum . Osteoblast cells beneath the periosteum in the diaphysial region facilitate the bone growth in diameter by a process called apposition.
Detailed explanation-3: -Appositional growth occurs when chondroblasts secrete new matrix along existing surfaces and this causes the cartilage to expand and widen. In interstitial growth, chondrocytes secrete new matrix within the cartilage and this causes it to grow in length.
