Teaching students about tone, mood and purpose will encourage students to analyze poetry in a more meaningful way; instead of students examining simply what is being said, students will be encouraged to analyze how and why it is being said.
Located in the main shaft of a long bone (consisting mostly of compact bone), the medullary cavity has walls composed of spongy bone (cancellous bone) and is lined with a thin, vascular membrane . However, the medullary cavity is the area inside any bone (long, flat, etc.) that holds the bone marrow.
Spongy (cancellous) bone is lighter and less dense than compact bone. Spongy bone consists of plates (trabeculae) and bars of bone adjacent to small, irregular cavities that contain red bone marrow.The canaliculi connect to the adjacent cavities, instead of a central haversian canal, to receive their blood supply.ompact bone consists of closely packed osteons or haversian systems. The osteon consists of a central canal called the osteonic (haversian) canal, which is surrounded by concentric rings (lamellae) of matrix. Between the rings of matrix, the bone cells (osteocytes) are located in spaces called lacunae.
