Document Summary
Lecture 4: bones and bone tissue. This shows that bone is alive. Females are more susceptible to osteoporosis (bone breakdown): proper nutrition and exercise can help maintain bone health. Bones can be classified by the type of bone tissue or by their general morphology. Feature dense bone with smaller spaces and usually forms the outside surface of the bone. Larger spaces with a web- like (trabecular) sponge. Greater in length than in width. Slightly curved for length (would fracture more easily if straight). Contain lots of yellow bone marrow. Somewhat cubed shaped and equal in length/width. These bones allow for more precise or intricate movements. Generally thin and composed of two parallel plates. Provide considerable protection and lots of surface areas for muscle attachment. Contain red bone marrow = blood cell generation. Complex shapes and thus cannot be grouped with the other bones. They are grouped in this. Other category for their oddity.
