Most endocrine tissues use a negative feedback mechanism for homeostasis. Which of the following involves a positive feedback mechanism? Group of answer choices cortisol insulin oxytocin thyroid

The correct answer is: Oxytocin.

Explanation:

Feedback mechanisms are key elements in the regulation of hormone release and, in the human body, most endocrine systems work by making use of negative feedback, which means that the response generated by the release of the peripheral hormone (for example, insulin), will lead to an inhibition of the stimulus that made the release of said hormone possible - this is very important to control homeostasis.

Positive feedback, on the other hand, is the opposite. This type of feedback mechanism, which is not as common as negative feedback, happens when the peripheral hormone is released and this stimulates the tissue that released the hormone that stimulated the release of the peripheral hormone - this is done so the hormone effect is amplified more and more.

To better illustrate these mechanisms, here are some examples of each:
