Meaning
Hormone released by the hypothalamus that controls the release of thyroid-stimulating hormone from the anterior pituitary.
Classification
Nouns denoting substances.
Examples
- The hypothalamus secretes thyrotropin-releasing factor, or trf, to stimulate the release of TSH from the anterior pituitary gland.
- Elevated trf levels stimulate the thyroid gland to produce more thyroid hormones, increasing metabolic rate.
- The researchers developed a technique to measure the levels of trf released by the hypothalamus in response to changes in blood glucose.
- The anterior pituitary gland receives trf signals from the hypothalamus and responds by releasing thyroid-stimulating hormone.
- In Addison's disease, trf levels are often elevated as the body attempts to compensate for decreased thyroid hormone production.
