A patient has tingling around the mouth, muscle cramps and a positive Trousseau sign after neck surgery. Which endocrine disturbance is most likely?
Correct answer: A. Reduced parathyroid hormone secretion
- A. Reduced parathyroid hormone secretion
- B. Increased adrenal medulla secretion
- C. Reduced pancreatic glucagon secretion
- D. Increased thyroid hormone secretion
Explanation
Injury or removal of the parathyroid glands can reduce parathyroid hormone, lowering blood calcium and causing neuromuscular irritability. The reported signs are not typical effects of excess thyroid hormone or altered adrenal medulla activity.

About Endocrine System
The endocrine system covers hormone-producing glands including the pituitary, thyroid, parathyroids, adrenals, pancreas, pineal gland, ovaries and testes. It explains hormone classes, target-cell responses, feedback control, and the functions of hormones such as insulin, thyroxine, cortisol, growth hormone and ADH, which is often confused with a kidney-produced substance.
