4. What protein fiber is flexible and makes up a major portion of bone? 5. Use this spot to include pictures of your two dissected chicken wings from step 19. Application Questions: 1. Place the following layers in order from most superficial (1) to deep (6). ______:Deep Fascia ______:Epidermis ______:Dermis ______:Superficial fascia ______:Bone ______:Muscle 2. Remove the chicken bone from the cup. What has happened to the strength of the bone after letting it sit in vinegar for 72 hours? Of the two substances you identified in review questions 2 and 3, which do you think dissolved in the vinegar? What substance is left over then? 3. What does the above tell you about how the bone needs to balance and role of these two substances? 4. Teeth are also composed of the substance you identified in review question 2. What do acidic substances such as sodas do to your teeth then? 5. Use this spot to include a picture of the bone that was dissolved in vinegar from step 24.

Step 1
The answer is collagen. Collagen provides a flexible framework that supports the minerals (calcium phosphate) that give bone its hardness. Show moreā¦

Answer the following questions: 1. Describe the differences between a fresh chicken bone, baked chicken bone, and an acid treated chicken bone. Your answer should be based on the histology and composition of bone. 2. Which bone is brittle? 3. What substance was damaged in brittle bone? Why does this increase bone breakage? 4. Which bone is the softest? 5. What substance has been lost from the soft bone? What clinical disorder is this bone simulating?

The functions of bone tissue follow its structure. In bone tissue, the strong collagen fibers give bones tensile strength (flexibility) and resistance to pulling force; while the inorganic salts (calcium hydroxyapatite and other mineral salts) give bones compression resistance (resistance to compression and heavy weights). If the bones are treated by the following treatments: Bones baked for 2 hours at 400Ā°F (hint for answering question: which component of bone tissue is destroyed by baking?) Bones soaked in 1M Nitric acid for 6 hours (which component of bones tissue is eaten away by acid?)
