Before the discovery of these glands, thyroid surgery often led to a rapid drop in blood calcium levels,which triggered muscle contractions and cardiac arrhythmias. What glands are these and which hormone is lacking?

Question

Quizplus · Accepted Answer

The glands being referred to are the parathyroid glands, which are responsible for producing parathyroid hormone. This hormone helps regulate calcium levels in the blood. Without it, as in the case of thyroid surgery, blood calcium levels can drop rapidly, leading to muscle contractions and cardiac arrhythmias. Calcitonin, levothyroxine, and the thyroid gland are not directly involved in regulating blood calcium levels.
