When the level of the particular hormone increases, the stimulating hormone level deceases and vice verse is there. So for example, when the level of the thyroid hormone increases, the level of the thyroid stimulating hormone decreases and vise verse. This is called as negative feed back system. This is how the negative feed back system works. In this type of regulation, you have a particular level of the hormone is set to have a desired level of the hormone, in your body. Some times this setting is changed. So you may have low level of the thyroid hormone or high level of the thyroid hormone is set, at your hand. This is probably done, some times, under the supervision of the higher centre called as hypothalamus. Hypothalamus is situated at the base of your brain. From hypothalamus, you get the releasing factors. In this case, the thyroid releasing factor. Many such factors regulate the 'setting' of hormone levels of your body. But again, this hypothalamus is not the 'ultimate' centre of regulation. Overall brain has direct or indirect effect on the hypothalamus. Your brain is not again the 'ultimate' centre of regulation. The brain is affected by genetic influence and have impact of the surrounding events on the same. All this is necessary for proper control of your homeostasis. Otherwise the thyroid could have secreted the hormone at particular pace regardless of any necessary control, for example.

Positive and negative feedback
Atrial natriuretic peptide.
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."
Insulin is a hormone produced by the beta cells in the pancreatic islets of Langerhans that stimulates glycolysis and increase glucose uptake in muscle and adipose tissue; therefore, it maintain homeostasis in the body by decreasing blood sugar level when it is high. It shows a negative feedback because the response negates the stimulus to maintain homeostasis.
Positive feedback speeds up reactions and negative feedback slows them down. In electronics and control systems, positive feedback means the feedback gets added to the input and then goes as output. And negative feedback means that the output is input minus feedback (from output). This is the most basic and layman answer I can think of. In social and business terms, a positive feedback means a good response ( a praise for a product, or interest generation among the clients) and a negative feedback means a bad response (unhappy clients, criticism and the like ).
Positive and negative feedback
no by negative feedback
Self-regulating system; information about effect of hormone that is fed back to gland, which then decreases secretion of that hormone; most common method of regulation
During positive feedback loop, e.g. a gland activates a hormone and the hormone in turn activates the gland. After the hormone knows that it is being activated by the gland, the hormone signals the gland to produce more of the hormone. This is positive feedback loop.
because an increase in insulin decrease the sugar level
you grow
There is no single answer to this question, but one common aspect is that most hormone release is in somehow regulated by a negative feedback system. For example a hormone produces an effect that in turn inhibits the same hormone's release. There are also positive feedback loops as in the rise of glucose acting to increase insulin release which then lowers glucose levels.
The combination of an endocrine gland and a hormone is a working endocrine gland that has a chemical messenger called a hormone. The hormone can be either manufactured by that gland itself, a stored hormone that another gland made, or it can be a positive or negative feedback hormone as part of the hormonal control system.

Negative feedback usually regulates hormone concentrations in the blood.
Through negative feedback when the amount of a particular hormone in he blood reaches a certain level the endocrine system sends signals that stop the release of hormone.
Negative feedback occurs when the output of a system reacts to cancel out the effects of an input of a system, as opposed to positive feedback (in which the actions/output is intensified or increased). The more negative, the more stable. Thus, with things being canceled out, the body maintains homeostasis. An example of negative feedback in action is the maintenance of blood glucose levels and body temperature. With input of sugar, insulin is released to stabilize the body (on the other hand, without insulin, diabetes can be diagnosed). With a raise in body temperature, blood vessels and pores are opened to release heat.
