Explanation / Answer

2-5
1.   Site of spongy bone in the adult Epiphysis
2.   Site of compact bone in the adult Diaphysis
3.   Site of hematopoiesis (blood cell formation) in the adult Red marrow cavity
4.   Scientific name for the shaft of long bone Diaphysis
5.   Site of fat storage in an adult Yellow marrow cavity
6.   Site of longitudinal growth in a child Epiphyseal plate.

2-6
1.   Formation of bone collar
2.   Cavitation of hyaline cartilage
3.   Invasion of internal cavities by periosteal bud and spongy bone formation
4.   Formation of medullary cavity and secondary ossification centers
5.   Ossification of epiphysis

2-7
1.   Osteoclast: An osteoclast is a multinucleate bone cell that is responsible for resorption of bone.
2.   Osteoblast: An osteoblast is a cell that is responsible for the formation of bone.
3.   Osteocyte: An osteocyte is a bone cell that is found in the spaces of a fully formed bone. It helps in the maintenance and integrity of the bone.
4.   Lacunae: It is the small space in the bone that contains the osteocytes.
5.   Canaliculi: Canaliculi are the microscopic canals that are found between the ossified bone lacunae.
6.   Lamellae: These are the concentric layers of an osteon that surround the haversian canal.
7.   Osteon: Osteon also known as the haversian system is the fundamental and functional unit of a much compact bone.
8.   Chondrocyte: Chondrocytes are the cells found in the cartilage connective tissue that are responsible for the formation and functionality of the cartilage.
