Answer
  • Bone resorption of Ca
  • Bone mineralisation of Ca
  • Increased Intestinal absorption of Ca
  • Increased renal reabsorption of Ca

Answer
  • 2.5
  • 2.8
  • 3.1
  • 3.4

  • 2.5
  • 2.8
  • 3.1
  • 3.4
  • 3.7

Question 9

Question
Which of the following is NOT correct: Tertiary hyperparathyroidism occurs because:
Answer
  • The parathyroids become unresponsive to calcium levels
  • Renal disease for long periods with low calcium leads to lack of parathyroid response to calcium levels
  • parathyroid glands which are continually secreting PTH for a long period of time eventually do not respond to negative feedback from calcium
  • Peripheral tissues which are continually subjected to high concentrations of PTH eventually do not respond to PTH
  • The parathyroid glands become autonomic
