Question

parathyroid hormone
what stimulates the release of parathyroid hormone (pth)?
low basal metabolic rate
hypercalcemia
hypocalcemia
cold temperatures

Explanation:

Parathyroid hormone (PTH) is released in response to low blood calcium levels (hypocalcemia). PTH acts to increase blood calcium levels by promoting calcium release from bones, enhancing calcium reabsorption in the kidneys, and facilitating calcium absorption in the intestines. Low basal metabolic rate is related to thyroid - related issues (e.g., hypothyroidism, not directly to PTH). Hypercalcemia would inhibit PTH release. Cold temperatures are more associated with the release of thyroid - stimulating hormone (to increase metabolic rate) rather than PTH.

Answer:

Hypocalcemia
