At least one instance of a negative feedback loop can be found in the growth hormone axis. So, this assertion is true.
Control of thyroid hormone secretion is a key instance of a negative feedback loop. Thyroxine and triiodothyronine, sometimes known as "T4 and T3," are thyroid hormones that are produced and secreted by the thyroid glands and have an impact on metabolism all over the body. The female menstrual cycle is controlled by a negative feedback loop involving brain regions. 2. The brain's hypothalamus has a gland that secretes gonadotropin-releasing hormone (GnRH).
The pituitary gland in the brain receives instructions from the GnRH to create follicle-stimulating hormone (FSH). The use of negative feedback loops in processes can be seen in homeostatic systems like: Thermoregulation (if body temperature varies, mechanisms are stimulated to restore normal levels) (if body temperature changes, mechanisms are induced to restore normal levels) blood sugar control (insulin lowers blood glucose when levels are high ; glucagon raises blood glucose when levels are low).
