ANATOMY

Detailed explanation-1: -Negative feedback mechanism normalizes the things when they start becoming too extreme. For eg., the thyroid gland is regulated by a negative feedback mechanism. The hormone secreted by the hypothalamus stimulates the pituitary gland to release thyroid stimulating hormone.

Detailed explanation-2: -Most hormones are controlled by negative feedback, in which the hormone feeds back to decrease its own production. This type of feedback brings things back to normal whenever they start to become too extreme. Positive feedback is much less common because it causes conditions to become increasingly extreme.

Detailed explanation-3: -After reaching the pituitary, TRH stimulates the release of TSH, which in turn promotes the production and release of T4 and T3 by the thyroid gland. Negative feed-back effects of T4 and T3 on both the hypothalamus and the pituitary regulate the HPT system.

Detailed explanation-4: -Negative feedback (or balancing feedback) occurs when some function of the output of a system, process, or mechanism is fed back in a manner that tends to reduce the fluctuations in the output, whether caused by changes in the input or by other disturbances.

Detailed explanation-5: -Positive and negative feedback mechanisms are two different types of feedback mechanisms. Positive feedback stimulates and increases hormone secretion. Negative feedback stops and inhibits the hormone from being produced.
