Wednesday, 3-1-Puberty & disorders of development and Menstrual disorders (Moulton) Flashcards

1
Q

1) as the corpus luteum dies, ___ levels fall –> 2) The pituitary responds to falling levels of #1 by increasing __ secretion –> 3) FSH recruits a cohort of large antral follicles to enter rapid growth phase. Follicles secrete large amounts of __ –> 4) The substances secreted by the follicles in #3 negatively feedback on FSH –> 5) declining FSH levels progressively cause atresia of all but 1 follicle-leading to selection of dominant follicle, which produces high levels of ___ –> 6) High estrogen has positive feedback on gonadotropes and leads to a __ surge –> 7) the surge in #6 induces meiotic maturation, ovulation, and luteinization. The corpus luteum produces high amounts of ___. –> 8) High levels of the substances produced by the corpus luteum in #7 feedback on __ to return to basal levels. –> 9) the __ progressively becomes less sensitive to basal LH and dies if levels of LH-like activity (i.e., hCG) do not increase

A

1) Estrogen and progesterone
2) FSH
3) Estrogen and inhibin
5) Estrogen
6) LH (and some FSH)
7) Progesterone, along with Estrogen and inhibin
