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.
After spongy bone is formed in the diaphysis, osteoclasts break down the newly formed bone to open up the medullary cavity. The cartilage in the epiphyses continues to grow so the developing bone increases in length. Later, usually after birth, secondary ossification centers form in the epiphyses.
