Pregunta 9
Pregunta
Which of the following is NOT correct:
Tertiary hyperparathyroidism occurs because:
Respuesta
-
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
