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.

Parathyroid glands is a negative or positive feed back?
The parathyroid glands are involved in negative feedback regulation of blood calcium levels. When blood calcium levels are low, the parathyroid glands release parathyroid hormone (PTH) to increase calcium levels by stimulating calcium release from bones, absorption from the intestines, and reabsorption from the kidneys. Once calcium levels are restored, the release of PTH is inhibited, demonstrating negative feedback control.
Is menstrual cycle a feedback mechanism?
Yes.The Menstrual cycle is a feedback mechanism because it is regulated by hormones which are controlled by negative feedback mechanisms. This mechanism includes hormones that are interacted with tissues in the menstrual cycle.
Is the ADH feedback loop an example of positive or negative feedback explain?
The ADH feedback loop is an example of a negative feedback loop. Negative feedback loops occur when the output of a system acts to oppose the changes to the input of the system. This is the case with ADH because when there is not enough water, the hypothalamus and pituitary gland work to release ADH so that the body can retain more water.
What effect does negative feedback have on homeostasis?
Imagine this process in the body: The brain tells your stomach to release chemical A. Chemical A causes Chemical B to be released. Chemical B has an effect on your body. Chemical B also tells the brain to stop releasing Chemical A. The negative feedback is Chemical B telling the brain to stop. If the brain keeps releasing chemical A, then chemical B will keep being released and do things to your body and it would never stop. This creates an imbalance. Therefore, the end products of any reaction in the body tell the source to
How are negative and positive feedback involved in homeostatic regulation?
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.
How can bone remodeling be controlled by negative feedback loop?
Bone remodeling can be controlled by a negative feedback loop through the regulation of osteoclast and osteoblast activity. When there is excessive bone resorption by osteoclasts, it triggers the release of signaling molecules that stimulate bone formation by osteoblasts to restore balance. This feedback mechanism helps maintain bone density and structural integrity.
What is a feed Back?
It depends on whether it is positive or negative feedback. Most biological organisms exhibit both negative and positive feedback, including humans. An example of positive feedback is contractions during childbirth. Negative feedback is blood sugar regulation based upon the release of insulin into the bloodstream at necessary times.
What is a biological feed back?
It depends on whether it is positive or negative feedback. Most biological organisms exhibit both negative and positive feedback, including humans. An example of positive feedback is contractions during childbirth. Negative feedback is blood sugar regulation based upon the release of insulin into the bloodstream at necessary times.
What are two types of feedback mechanisms found in living organisms?
Positive feedback amplifies a response in the same direction, such as the release of oxytocin during childbirth. Negative feedback regulates a response by counteracting changes, like temperature regulation in the body.
Parathyroid glands is a negative or positive feed back?
The parathyroid glands are involved in negative feedback regulation of blood calcium levels. When blood calcium levels are low, the parathyroid glands release parathyroid hormone (PTH) to increase calcium levels by stimulating calcium release from bones, absorption from the intestines, and reabsorption from the kidneys. Once calcium levels are restored, the release of PTH is inhibited, demonstrating negative feedback control.
How is epinephrine controlled?
Epinephrine is controlled through a negative feedback system involving the hypothalamus, pituitary gland, and adrenal glands. When the body perceives stress or danger, the hypothalamus signals the pituitary gland to release adrenocorticotropic hormone, which in turn stimulates the adrenal glands to produce and release epinephrine. Once the epinephrine levels are sufficient to address the stressor, the negative feedback loop is activated to reduce further release.
Is menstrual cycle a feedback mechanism?
Yes.The Menstrual cycle is a feedback mechanism because it is regulated by hormones which are controlled by negative feedback mechanisms. This mechanism includes hormones that are interacted with tissues in the menstrual cycle.
Is the ADH feedback loop an example of positive or negative feedback?

This is the case with ADH because when there is not enough water, the hypothalamus and pituitary gland work to release ADH so that the body can retain more water.
Hormone concentration levels are most commonly controlled by?
There are three mechanisms which govern hormone release; hormonal, humoral, and neural. Hormonal release means that one hormone will trigger the release of a second hormone. An example of this would be thyroid-releasing hormone from the anterior pituitary causing the release of thyroid hormone from, er, the thyroid. Humoral release is triggered by the presence of certain ions or nutrients in the blood stream. Insulin is an example of humoral release because it is triggered by the presence of glucose in the bloodstream. Finally neural release is a release caused by the nervous system directly. A good example of that would be the release of adrenaline (epinephrine) from the adrenal glands by the sympathetic nervous system.
Is the ADH feedback loop an example of positive or negative feedback explain?

This is the case with ADH because when there is not enough water, the hypothalamus and pituitary gland work to release ADH so that the body can retain more water.
How does the endocrines system's negative feedback system work?
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.
