Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Hormone regulation operates under which type of feedback mechanism?
A
positive feedback
B
negative feedback
C
zero feedback
D
Hormones are not regulated
Explanation: 

Detailed explanation-1: -Most hormones are controlled by negative feedback, in which the hormone feeds back to decrease its own production. This type of feedback brings things back to normal whenever they start to become too extreme. Positive feedback is much less common because it causes conditions to become increasingly extreme.

Detailed explanation-2: -Hormone production and release are primarily controlled by negative feedback. In negative feedback systems, a stimulus elicits the release of a substance; once the substance reaches a certain level, it sends a signal that stops further release of the substance.

Detailed explanation-3: -The hormone feedback mechanism is defined as the mechanism that is used to maintain the hormone balance in the blood / body. The increase or decrease in the concentration of that hormone can sometimes stimulate and increase the secretion of that hormone or inhibit the secretion of the hormone. It’s called feedback.

Detailed explanation-4: -Positive and negative feedback mechanisms are two different types of feedback mechanisms. Positive feedback stimulates and increases hormone secretion. Negative feedback stops and inhibits the hormone from being produced.

Detailed explanation-5: -…a prime example of a negative feedback control system. The production and secretion of thyroxine and triiodothyronine by the thyroid gland are stimulated by the hypothalamic hormone thyrotropin-releasing hormone and the anterior pituitary hormone thyrotropin.
