Positive feedback and negative feedback difference (hormone control)??????????

So positive feedback means releasing a hormone until the problem goes away (ex. oxytocin). Negative feedback means releasing a hormone until another hormone comes to shut it off (ex. calcitonin and parathyroid hormone) or until the problem goes away (ex. epinephrine).

Did i get this right? Because then wouldn't epinephrine be a positive feedback because it continues to be released until the stressful situation goes away, but i know this is negative feedback.....where did i go wrong? Please explain. Thanks so much!!!!!!!!

You are a bit confused about the feedback loop mechanism. A positive feedback loop is where a hormone promotes the release of itself. For example, your body releases a little bit oxytocin. That oxytocin is recognized by a gland which responds by releasing more oxytocin. Epinephine is NOT a positive feedback because it does not stimulate the adrenal gland to release more epinephine.

A negative feedback loop is where a hormone stimulates the release of a different hormone that inhibits the release of the first hormone. This prevents a hormone from being released when you already have enough in your system.
