Thyroxine is the main hormone released by the thyroid gland. Increases the basal (resting) metabolic rate.
Responsible for regulating the growth and brain development of young animals.
Production of thyroxine is regulated by a negative feedback loop.
Levels are too low:
- The production of TSH is increased. This stiumaltes the release of thyroxine
Levels are too high:
- The production of TSH is decreased. This relaxes the stimulation of the release of thyroxine
(TSH = thyroid-stimulating hormone)
