What does the feedback loop for Vincent look like? Be sure to indicate all the hormones and glands involved in the feedback loop. Indicate whether the hormone levels are increasing or decreasing.

For example, the white texts can only be dragged into a white coloured box. Also, words may be used more than once. increased levels of estrogen and progesterone will result in ( negative, positive, increase, decrease) feedback to the hypothalamus and anterior pituitary to ( negative, positive, increase, decrease), ( LH, FSH, GnRh, LH AND FSH) production. This normally occurs during the ( FOLLICULAR STAGE, LUTEAL STAGE ) Decreased levels of estrogen and progesterone will result in ( negative, positive, increase, decrease) feedback to the hypothalamus and anterior pituitary to ( negative, positive, increase, decrease), (LH, FSH, GnRh, LH AND FSH) production. This normally occurs during the ( FOLLICULAR STAGE, LUTEAL STAGE ). Extremely high levels of estrogen near the end of the follicular phase will result in ( negative,…
