During the follicular stage of menstruation, increased estradiol production causes an increase in FSH production. This increase in FSH production by the anterior pituitary gland will have what effect on the follicle?
A)
The follicle will continue to grow until it can no longer stay in its membrane.
B)
The follicle will die, which results in a fall of FSH.
C)
The follicle will continue to grow and produce estradiol.
D)
The follicle will secrete additional hormones to attract swimming sperm.
Ans:
B
Feedback:
In positive feedback control, rising levels of a hormone cause another gland to release a hormone that is stimulating to the first. Increased estradiol production during the follicular stage of the menstrual cycle causes increased FSH production by the anterior pituitary gland. This stimulates further increases in estradiol levels until the demise of the follicle.
