Compact bone consists of concentric rings or (lamellae / canaliculi), with bone cells called (chondrocytes / osteocytes), located in tiny spaces called (divots / lacuna / cavaties). Nutrients in blood and nerves travel through osteons by (haversian canal / lamellae / canaliculi) and then capillaries reach each osteocytes by tiny, radiating canals called (haversian canal / lamellae / canaliculi). Spongy bone (does / does not) have osteons. Spongy bones consists of bony bars and plates termed (lattice / trabeculae / osteons).

Where would you expect to find spongy bone in a long bone? What are its functions? (page 230 )
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.
