Can you Asses the reason hormone feedback systems are referred to as negative feedback?
When a drop in the level of hormones in the body occurs, it causes a chain reaction of responses. It is called negativefeedback because it causes system output to oppose system input, rather than support it.Example: Thyroxine (a thyroid hormone) level in the blood drops. The hypothalamus then sends out an order for TSH (thyroid stimulating hormone) to the anterior pituitary gland. The pituitary releases the TSH. TSH then causes the thyroid to start producing thyroxine again. When the blood level rises, the hypothalamus stops producing TSH, causing the thyroid to stop producing thyroxine. This happens in a loop until stabilization occurs.
