Richard had symptoms of excessive secretion of PTH (high blood calcium levels), and his physicians were certain he had a parathyroid gland tumor. Yet when surgery was performed on his neck, the surgeon could not find the parathyroid glands at all. Where should the surgeon look next to find the tumorous parathyroid gland?
Which hormone acts to raise blood calcium levels, when they are too low?
A) TH (T3 and T4)
B) PTH
C) Calcitonin
D) Cortisol
