A tumor in an endocrine gland caused Jane to have weakened bones and unusually high levels of blood calcium. Which of the following was affected?

Question

Quizplus · Accepted Answer

The high levels of blood calcium and weakened bones suggest that the tumor is causing overproduction of parathyroid hormone (PTH), which is produced by the parathyroid glands. PTH regulates calcium levels in the blood and can cause bone resorption to increase blood calcium levels when it is overproduced. The other endocrine glands listed (thyroid, pituitary) do not have a direct role in regulating blood calcium levels or bone strength. Bone marrow is responsible for producing blood cells, but would not directly cause the symptoms described.
