Question
"Osteoporosis is a common disease that is characterized by low bone mass with microarchitectural disruption and skeletal fragility, resulting in an increased risk of fracture, particularly at the spine, hip, wrist, humerus, and pelvis." Describe the contrasting roles of calcitonin and parathyroid hormone on calcium homeostasis How are "osteopenia" and "osteoporosis" different? What are the risk factors for developing osteoporosis? What are some of the molecular/cellular mechanisms that are "disrupted" in this condition? Why are the identified skeletal regions (spine, hip, etc.) more susceptible to damage? Describe the procedure of Kyphoplasty" Name three common treatments (pharmacological or behavioral) used to treat osteoporosis.Explanation / Answer
Ans-1 Calcitonin and parathormone are antagonistic to each other. Calcitonin is calcium lowering hormone while parathormone is calcium increasing hormone. Calcitonin increase the calcium absorption , decrease the activity of osteoclasts and parathormone increases activity of osteoclasts. Ans-2. In both the cases the protein content and calcium level decreases but osteoporosis is more severe than osteopenia. Ans-3 risk factors are like age, gender as the females are more susceptible, bone structure, body weight etc.
