Osteoclast activity would decrease when ________ levels are elevated.
A) parathyroid hormone
B) vitamin D
C) calcitonin
D) growth hormone
E) vitamin C
Osteoclast Activity
The process involving osteoclast cells that break down bone tissue, playing a critical role in bone remodeling and calcium homeostasis.
Calcitonin
This is a chemical released by the thyroid gland, essential for managing the calcium levels in the bloodstream.
Elevated Levels
Refers to quantities that are higher than normal, often implying a potential health risk or abnormal state in a clinical context.
- Gain an understanding of the roles played by osteoblasts, osteocytes, and osteoclasts in bone growth, preservation, and mending.
- Grasp the impact of specific hormones on calcium homeostasis and bone metabolism.

Final Answer :
C
Explanation :
Calcitonin is a hormone produced by the thyroid gland that works to lower blood calcium levels. It does this by inhibiting osteoclast activity, which are the cells responsible for bone resorption. When calcitonin levels are elevated, it means that the activity of osteoclasts is decreased, leading to a reduction in the breakdown of bone and a decrease in the release of calcium into the bloodstream.
