ANATOMY

Detailed explanation-1: -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. Appositional growth occurs mainly at the endosteum and periosteum.

Detailed explanation-2: -In interstitial growth, chondrocytes secrete new matrix within the cartilage and this causes it to grow in length. Both types of growth can be seen in the growing bones of children and teenagers before they reach adulthood.

Detailed explanation-3: -In endochondral ossification, bone develops by replacing hyaline cartilage. Activity in the epiphyseal plate enables bones to grow in length (this is interstitial growth). Appositional growth allows bones to grow in diameter. Remodeling occurs as bone is resorbed and replaced by new bone.

Detailed explanation-4: -Interstitial growth is a bone growth which results in the lengthening of the bone. This growth occurs within the lacunae. It happens due to the cell division in the proliferative zone and the maturation of cells in the zone of maturation. Cartilage lengthens and is replaced by bone tissue during interstitial growth.

Detailed explanation-5: -Interstitial growth is the process that adds or removes solid mass at locations inside a solid material. For this process to occur, there must be interstitial space within this material to allow atoms or molecules to bind to the underlying substrate.
