When blood calcium levels are high, osteoclast activity is Blank______.Multiple choice question.stimulatedinhibited

Analyzing the Question

1. Understanding the Process: The regulation of blood calcium levels is largely controlled by hormones such as parathyroid hormone (PTH) and calcitonin. High blood calcium levels indicate that there is an excess of calcium in the bloodstream.

2. Role of Osteoclasts: Osteoclasts are cells responsible for bone resorption, meaning they break down bone tissue and release calcium into the bloodstream.

Relevant Concepts

1. Hormonal Regulation: When blood calcium levels rise, calcitonin is released from the thyroid gland, which inhibits osteoclast activity to reduce blood calcium levels.

2. Impact on Osteoclast Activity: In the presence of high calcium levels, the body aims to lower these levels by inhibiting the function of osteoclasts.

Final Answer

When blood calcium levels are high, osteoclast activity is inhibited.
