Question

A parathyroid gland that is unresponsive to blood calcium levels and that produces abnormally high amounts of parathyroid hormone, would result in bones rapidly breaking down.

Quizplus · Accepted Answer

This is true. Parathyroid hormone is responsible for regulating blood calcium levels, and when it is produced excessively due to an unresponsive parathyroid gland, it can cause the breakdown of bones through a process called osteoclast activation. This condition is known as hyperparathyroidism.
