Answer to Question 1

ANS: A, C, D
Vitamin D is needed to absorb calcium and phosphorus. A deficiency of vitamin D can lead to rickets. Estrogen stimulates osteoblastic activity. Parathyroid hormone stimulates osteoclastic activity. Calcitonin decreases serum calcium levels when they get too high. Thyroxine increases the rate of protein synthesis in all tissue types.

Answer to Question 2

ANS: A, C, E
Many age-related changes occur in the musculoskeletal system, including decreased bone density, degeneration of cartilage, and some degree of muscle tissue atrophy. Osteoporosis, while common, is not universal. Bone density decreases with age, not increases.
