Thyroxine is the precursor to active thyroid hormone, which is essential for life. Thyroid hormone also plays an important role in brain development. A child with untreated low thyroid hormone (hypothyroidism) will develop a condition known as cretinism, which is marked by severe physical and mental abnormalities.

How does negative feedback regulate the amount of thyroxine in the blood?
blood level gets low
Regulation of the release of T3 and T4 from the thyroid gland is controlled by negative feedback?
When the level of the thyroxine increase, the level of the thyroid stimulating hormone decrease. So in turn the level of the thyroid hormone decreases. When the level of the thyroxine decrease, the level of the thyroid stimulating hormone increase. This in turn increase the level of the thyroxine. This explanation does not explain to how the level of the hormone is regulated at that particular level. But then this explanation satisfy most of the people.

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.
How does a negative feedback system work explain how negative feedback regulates the amount of thyroxine in the blood?
When the amount of a particular hormone in the blood is reaches a certain level, the endocrine system sends signals to stop the release of that hormone. "Pearson Education Inc."
