The hypothalamus releases hormones called releasing hormones. Some of the hormones they release also inhibit hormone release. So, the hypothalamus can either release:
- Releasing hormones, OR
- Release inhibiting hormones
These hormoens act on the aerior pituitary which ccuses the release oftrophic hrmones which are specific for target organs ie. Sex glands, thyroid glands, adrenal glands.
The target glands release the hormone itself, which are called the non-trophic hormones. These hormones are responsible for causing a physiological effect. The hypothalamus is under the control of external stimulus ie. stress, the CNS, diet, and the immune system.
Lots of things can control the release of releasing and release inhibitory hormones from the hypothalamus. At each level you have feedback inhibition. You get positive and negative input on the hypothalamus from outside the endocrine system and you get mostly negative influence on the hypothalamus from the anterior pituitary and the target organs.
The trophic hormones can feedback and inhibit the hypothalamus. Even the physiological response to the hormone can feedback and affect target organs. This whole feedback loop is negative, but it can also be ostive. So, if hormone levels drop, or if stress increases, or diet changes, there will be a change in physiological response that will make feedback positive or negative to affect the hypothalamus.
Negative feedback regulates endocrine activity by telling the endocrine gland when to decrease hormone production. As the level of the hormone in the bloodstream increases, the gland decreases production.

What are the feedback mechanisms that regulate hormone levels in the body?
Positive and negative feedback
What is the endocrine definition of self-regulating?
Self-regulating in the endocrine system refers to the ability of glands to adjust hormone production based on feedback received from the body. This feedback can come from hormone levels in the blood or other signals, allowing the glands to maintain balance and respond to changing conditions. This process helps to keep hormone levels within a tightly controlled range to support optimal functioning of the body.
What factors control blood hormone levels?
Blood hormone levels are primarily regulated by a complex interplay of feedback mechanisms involving the endocrine glands and the nervous system. Factors such as stress, sleep, exercise, diet, and age can also influence hormone levels. Hormones themselves can also regulate their own production through negative feedback loops.
What is the endocrine feedback loop?
The endocrine feedback loop is a system in the body that regulates the release of hormones. When hormone levels deviate from a set point, feedback mechanisms signal the endocrine glands to either increase or decrease hormone production in order to maintain homeostasis. This helps ensure that the body's internal environment remains stable.
How does negative feedback control hormone levels?

Use hormone and feedback in the same sentence?
Hormones are released in response to feedback mechanisms that help regulate various physiological processes in the body.
Which hormone stimulates the production of testosterone?
Hormones are regulated by what are called negative feedback mechanisms. When more is needed, more will be released and the opposite is true when there is enough. For example, the secretion of follicle-stimulating hormone decreases as the amount of circulating estrogen increases.
Does increased thyroid hormone production increase or decrease TSH production?
Increased thyroid hormone production decreases TSH production through negative feedback. When thyroid hormone levels rise, they signal the pituitary gland to reduce its production of TSH, which in turn slows down the release of more thyroid hormones.
What do you think would happen to the level of a hormone in the blood if negative feedback didn't happen?
If negative feedback did not occur, the hormone level in the blood would likely continue to increase. Negative feedback mechanisms control hormones by signaling the body to stop producing them once they reach a certain level. Without this regulation, hormone levels could become dangerously high or low, leading to health issues.
What is the hormonal feedback loop?
The hormonal feedback loop is a regulatory system in the body that involves the release of hormones to control the levels of specific hormones in the blood. When hormone levels reach a certain threshold, signals are sent to either increase or decrease the production of that hormone to maintain balance in the body. This feedback loop helps ensure that hormone levels remain within a narrow range to avoid overproduction or underproduction of hormones.
What effect does oestrogen have on the production have on the follicle hormone?
it reduces the levels of FSH - negative feedback loop
Control of hormone secretions is essential to maintain?
proper physiological function and homeostasis in the body. Hormone secretions are tightly regulated by various feedback mechanisms involving the endocrine system, nervous system, and other physiological processes. Imbalances in hormone secretion can lead to numerous health issues and dysfunctions in the body.
