An X-ray of the right femur in a child shows that it is shorter than the opposite femur, and below the average length for a child of this age. Which region of the bone is most likely to have caused this abnormality? (A) Diaphysis (B) Metaphysis (C) Epiphysis (D) Periosteum
Provides nutrients to bone. Lubrication of joint. Protects articular cartilages. Shock absorption. Endosteum is characterized as layers of bony matrix inside the diaphysis. The cellular layer that surrounds the diaphysis. Blood vessels that pass across multiple osteons. Spongy bone is produced in the diaphysis. Bone forms in the epiphysis. A periosteal bone collar forms around the diaphysis. Blood vessels innervate the center of the diaphysis. The epiphyseal plate forms. A rounded passage or hole through a bone is called a ramus. Foramen. Linea. Tubercle. Facet. Which of the following bones is classified as "irregular" in shape? Radius. Frontal. Sphenoid. Carpal. Ulna. Which bone is produced by endochondral ossification? Ethmoid. Patella. Atlas. Parietal. Tibia. The lacunae of osseous tissue contain blood cells. Osteocytes. Chondroblasts. Bone marrow. Capillaries.

3. Development of primary marrow cavity and secondary ossification center: (cells) arrive and degrade calcified tissue at center of diaphysis creating the; (cells) arrive and lay down layers of new compact bone at the border of the marrow cavity, thickening the shaft; marrow cavity enlarges longitudinally; cartilage begins to deteriorate next at the, creating secondary ossification centers at the ends of the developing bone. 4. Development of secondary marrow cavity: two regions form at the much like occurred along the diaphysis; one secondary marrow cavity typically forms faster than the other (see Step 4 in Fig. 7.9) 5. Epiphyseal Plate of infant/child: epiphyses of bone becomes filled with bone, except at the extreme ends of the bone where a lining of is found and also at the, which is a plate of retained hyaline cartilage responsible for continued longitudinal growth of the bone. 6. Adult bone: full transition occurs in late to early when all remaining cartilage of the transitions to bone and now is referred to as the.
