    LH&GnRH: "Triggures release of progestorone"
    Progesterone: "you are the cause of your own demise"

    Thank you! It took you a little over 6 minutes to get me to understand what my a&p professor spent 3 days on and half of the class (myself included) had no idea what the difference was.

    Best example given! What a paradoxical example, this same three organs does perform positive feedback as well as negative feedback if progesterone comes into action. Best example mam!

    well described, thank you. i have used your drawing as a revision reference! but the 'ovary' looks like a fallopian tube? and you have drawn an ovary but it looks like the oestrogen is coming out from the fallopian tube...just saying ;)

    But either feedback mechanisms can either decrease or increase the product, I think the concept you're presenting is a part of the definition or the function of these mechanisms.

  • @linaalmahmoud696
    @linaalmahmoud696 Před 8 lety +3

    now that was phenomenon .. but is it obligatory to have negative feedback against positive feed back - together- always or each can work individually ?thank you :)

    @meerhajji381 Před 6 lety

    But what about all other hormone
    The hard thing about feedbacks is that each hormone have different concept and path to take it like
    TSH or FSH and LH for male !😫😪

    thank you so much but what happened to estrogen? is lowing the LH can high the value of the progesterone? then when it is too low, it will wake up again the estrogen? am i correct?
