Which of the following are TRUE?
Select one or more: At the beginning of the menstrual cycle, FSH and LH stimulate the development of tertiary ovarian follicles, which begin to produce estrogen. Because of increased estrogen from the ovarian follicles, an LH surge occurs, triggering ovulation.
Mittelschmerz is the pain associated with ovulation.
After ovulation, under the influence of LH, a gland is formed from the follicle cells left behind in the ovary. It is called the corpus luteum. The corpus luteum secretes progesterone and estrogen, preparing the endometrium for potential pregnancy. Increased levels of estrogen and progesterone inhibit FSH and LH secretion from the anterior pituitary.
Which of the following are TRUE regarding the development of follicles?
Select one or more: It takes about a year for a primordial follicle to develop and become a growing tertiary follicle.
Primordial follicles are formed in utero.
Tertiary follicles respond to FSH because they have a FSH receptor. Primary follicles also respond to FSH because they have a FSH receptor. Tertiary follicles die via atresia, but primordial follicles do not undergo atresia.
When does positive feedback occur during the menstrual cycle?
Select one: During menstruation, around the middle of the follicular phase, around the time of ovulation, during the luteal phase.
