The thyroid gland is one component of the hypothalamic-pituitary-thyroid axis, which is a prime example of a negative feedback control system. The production and secretion of thyroxine and triiodothyronine by the thyroid gland are stimulated by the hypothalamic hormone thyrotropin-releasing hormone and the anterior pituitary hormone thyrotropin.
Positive and Negative Feedback Loops. Paul Andersen explains how feedback loops allow living organisms to maintain homeostasis. He uses thermoregulation in mammals to explain how a negative feedback loop functions.He uses fruit ripening to explain how a positive feedback loop functions. He also explains what can happen when a feedback loop is altered.e uses thermoregulation in mammals to explain how a negative feedback loop functions.
