dense irregular connective tissue. Predict the consequences of this condition on bone health, and
explain yout teasoning 2 A carcinoma is a cancer of epithelium, and a sarcoma is a cancer of
connective tissue. Are bone tumors carcinamas or sarcomas? Explain. 3 The condition
osteopetrosis is characterized by defective osteoclasts and a resulting decrease in osteoclast
activity. This causes osteoblasts to lay down excessive bone with abnomal osteon structure.
Interestingly, this disease increases the risk for fractures. Why do you think esteopetrosis would
increase fracture risk? 4 Mainutntion is a condition resulting from a diet deficient in calories,
macronutrients such as protein and carbohydrates, and/or vitamins and minerals. Malnutrition is
associated with many different bone diseases due to its effect on the bone extracellular matrix. a
Predict the effect on bone health of a diet deficient in minerals such as calcium salts. Of the three
bone samples you tested in Exercise 7-2, which one would most resemble a diet deficient in
calcium salts? Explain. b Predict the effect on bone health of a diet deficient in protein. Of the
three bone samples you tested in Exercise 7.2, which one would most resemble a diet deficient in
protein? Explain. c. Vitamin D is required for the absomption and deposition of calcium ions.
Vitamin C is required for the synthesis of the protein collagen. Predict the effect on bone health
of a diet deficient in vitamins D and C . A common fracture seen in children is a fracture of the
epiphyseal plate. a Why do you think the epiphyseal plate fractures more easily than other parts

2. of a bone? b Some epiphyseal plate fractures aee compression fractures, meaning the plate has
been crushed. Predict the long-term potential consequences of such a fracture.
