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.
How does a negative feedback system work explain how negative feedback regulates the amount of thyroxine in the blood?
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."
When a person eats a hormone is released. this hormone signals the stomach to start breaking down the food?

How are hormones kept at the correct level to match the human bodys needs?
Hormone levels are regulated through a feedback system involving the endocrine glands. When the body detects a need for a particular hormone, such as in response to stress or low blood sugar, signals are sent to the endocrine glands to release the hormone. Once the hormone reaches the desired level, signals are sent to stop its production, maintaining balance in the body.
Hormone production is self regulated by which mechanism?
Hormone production is self-regulated through a negative feedback mechanism. This means that when hormone levels in the blood reach a certain threshold, the body signals the glands to stop producing that hormone until levels drop back down. This helps maintain a balance of hormones in the body.
How can the hypothalamus receive signals from both the nervous and endocrine systems?
The hypothalamus connects the nervous system to the endocrine system, the hypothalamus receives the signal from the internal/external environments and then send chemical signals to the endocrine system to release the needed hormone for a particular function. So the hypothalamus does not receive signal from both, but transmits the signal to the endocrine system.
What type of stimulis is it when endocrine organs are prodded into action by other hormones?
This type of stimulus is called hormonal stimulation. It occurs when one hormone signals another endocrine gland to release its own hormone to regulate physiological processes in the body.
How do the signals of the endocrine system get transmitted to their appropriate target cells?
The endocrine system is a system of glands that secrete hormones (made of proteins) into the blood stream. Once in the blood, these hormones bind to other protein called receptors in the membranes of the target cells. This is how signals are transmitted
How are hormone levels monitored and controlled?
Controlled largley by negative feedback, when hormone levels rise, signals are transmitted to the endocrine organ, releasing the hormone, telling the organ to decrease the amount of hormone released.
Is acetylcholine a hormone?
No, it is a neurotransmitter. A hormone, is a compound produced by an endocrine gland and released into the bloodstream. A neurotransmitters are chemicals that transmit signals from a neuron to a target cell across the synapse and most are synthesized at the nerve terminals.
Does the endocrine system often run on negative feed back?
Endocrine system usually uses the negative feed back mechanism. So suppose when thyroid stimulating hormone is released, then thyroid hormones are released. They reduce the secretion of thyroid stimulating hormone. This is how the secretions of the hormones is regulated. In positive feed back mechanism, the level of both the hormones will raise and will create lot of problems.
What is the endocrine controlled by?
The endocrine system is controlled by signals from the brain, particularly the hypothalamus and pituitary gland. These structures release hormones that travel through the bloodstream and regulate the activity of various endocrine glands in the body. Hormone levels are tightly regulated through feedback mechanisms to maintain balance in the body.
