Detailed explanation-1: -Oxytocin is one of a few hormones that have a positive feedback loop. This means that the release of oxytocin leads to actions that stimulate your pituitary gland to release even more of it.
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: -Some endocrine glands secrete hormones in response to other hormones. The hormones that cause secretion of other hormones are called tropic hormones. A hormone from gland A causes gland B to secrete its hormone.
Detailed explanation-4: -Positive feedback is amplifying or magnifying the change or output. The response effect is magnified so that it can occur much faster. In this form of feedback, the output of the system is enhanced. Conversely, in negative feedback, the output is decreased or inhibited.
