LECTURE #19 - High Circulating Calcium Response Flashcards
1
Q
What hormonal response occurs in reaction to high circulating calcium?
A
The thyroid gland releases calcitonin, which inhibits the release of PTH from the parathyroid gland and the activity of osteoclasts.

Q
How does calcitonin influence calcium levels in the body?
A
Calcitonin lowers circulating calcium levels by suppressing PTH release and inhibiting osteoclasts, thereby reducing bone resorption.

Q
What are the effects of calcium-sensing receptors on the parathyroid gland?
A
When these receptors detect low circulating calcium, they trigger the release of PTH; when they detect high levels, they respond to inhibit PTH release.
