Final answer:
The two hormones from the anterior pituitary that stimulate the ovarian cycle are luteinizing hormone (LH) and follicle-stimulating hormone (FSH), both of which are essential for follicular growth and ovulation.
Step-by-step explanation:
The two hormones from the anterior pituitary that stimulate the ovarian cycle are luteinizing hormone (LH) and follicle-stimulating hormone (FSH). These hormones are vital for the proper functioning of the ovarian cycle. Gonadotropin-releasing hormone (GnRH) from the hypothalamus triggers the anterior pituitary to release these hormones. LH and FSH then travel through the bloodstream to the ovaries, where they stimulate the growth and maturation of ovarian follicles. FSH is responsible for the growth of the follicles, while LH triggers the release of estradiol, a type of estrogen, by the granulosa and theca cells of the follicles during the follicular phase of the ovarian cycle. The surge in LH also leads to ovulation, the release of the mature egg from the dominant follicle.
