What is the role of negative feedback in the endocrine system?

The

endocrine system controls important body functions such as temperature and metabolism, control of body hormones. These hormones are excreted into the blood by endocrine organs such as pituitary gland, thyroid and adrenal glands before traveling to their target tissues. What is called negative feedback regulates the amount of hormones available detection when blood levels rise above the threshold and inhibit hormone production. This prevents blood hormones from growing in constant growth, which could lead to disease.

Although positive feedback occurs, negative feedback in the endocrine system is much more common. The process of negative feedback is sometimes compared to the house heating system, where temperatures above a certain level are detected by a thermostat. This pulls out the heating until the temperature falls below the minimum threshold when the heating turns on again. Negative feedback leads to the production of hormones of sWSVARY and shutdown and generate hormone secretion pulses. This means that blood levels hOrmones grow and decrease cyclically, in a relatively narrow normal range.

An example of negative feedback in the endocrine system can be seen in the regulation of thyroid hormones. It begins with a brain hypothalamus that produces a thyroid hormone (market). This hormone moves to a nearby pituitary and causes the production of the thyroid stimulating hormone (TSH), which is then released into the bloodstream. After reaching the thyroid gland, it stimulates TSH cells to secrete thyroid hormones. These are important hormones that affect physiology of virtually all cell cells.

When the level of thyroid hormones reaches the upper threshold, the cells in the hypothalamus are affected that create and secrete the market. As a result, the market, then TSH and ultimately thyroid levels decrease. Once the level of thyroid hormones drops below the lower threshold, negative feedback ends. It meansthat the market is again produced by a hypothalamus, which leads to renewed secretion of TSH and synthesis and release of thyroid hormones.

hormonal production of many endocrine glands is associated with control of negative feedback. In addition to the loops of feedback, hormone secretion may affect. One example is the increase in secretion market, which is observed in a small child who is in a cold environment. It is assumed that this mechanism is the result of thyroid hormone capacity to regulate body temperature.
