Long bones are important for skeletal mobility. It consists of the femur, tibia, fibulae of the legs, etc. The long bones grow primarily from diaphysis elongation and at the end of growing bone with epiphysis.
A.
1. The area of the long bone which is covered with cartilage is called as an epiphysis. The ends of epiphysis are covered with articular cartilages.
2. Hyaline type of cartilage is articular cartilage which covers the end of the epiphysis of the long bone.
3. The area of epiphysis is made up of a thin layer of compact bone and a thick layer of spongy bone.
4. The area of diaphysis is made up of a thick layer of compact bone and a thin layer of spongy bone.
5. The epiphyseal plate would be present instead of the epiphyseal line in the long bone of the child.
B.
1. The bone cell which is found in lacuna is called as an osteocyte.
2. The vertical canal in an osteon is Haversian central canal.
3. The cavity that contains yellow marrow in adults is the medullary cavity.
4. The bone shaft refers to diaphysis.
5. The spaces where osteocytes are located is lacuna.
6. The horizontal canal in an osteon Volkmann's perforating canal.
7. The small canal connecting lacunae is canaliculi.
8. The membrane lining medullary cavity is endosteum.
9. The membrane covering the surface of the bone is periosteum.
10. The thin bony columns in spongy bone are trabeculae.
