Thyrotropic feedback control on a more detailed and quantitative level. [3] Thyroid homeostasis results from a multi-loop feedback system that is found in virtually all higher vertebrates. Proper function of thyrotropic feedback control is indispensable for growth, differentiation, reproduction and intelligence.

The concentration of thyroid hormones (T 3 and T 4) in the blood regulates the pituitary release of TSH; when T 3 and T 4 concentrations are low, the production of TSH is increased, and, conversely, when T 3 and T 4 concentrations are high, TSH production is decreased. This is an example of a negative feedback loop. [5]
English: An important negative feedback mechanism in human beings is the ability to maintain body temperature. When the body temperature is too high or too low, the blood vessels will change size accordingly to bring the body’s temperature back to normal.
The thyroid, or thyroid gland, is an endocrine gland in vertebrates. In humans, it is a butterfly-shaped gland located in the neck below the Adam's apple. It consists of two connected lobes. The lower two thirds of the lobes are connected by a thin band of tissue called the isthmus (pl.: isthmi).
At 20 weeks, the fetus is able to implement feedback mechanisms for the production of thyroid hormones. During fetal development, T 4 is the major thyroid hormone being produced while triiodothyronine (T 3 ) and its inactive derivative, reverse T 3 , are not detected until the third trimester.
12 Negative Feedback Examples And How To Give It. I have some bad news. If you want to be a good manager, or even team member for that matter, you’ll need to get comfortable giving negative ...
Perceptual control theory (PCT) is a model of behavior based on the properties of negative feedback control loops. A control loop maintains a sensed variable at or near a reference value by means of the effects of its outputs upon that variable, as mediated by physical properties of the environment.
