Menstrual Cycle - correct answer ✔Composed of:
-Ovarian cycle
-Endometrial cycle


Ovarian Cycle - correct answer ✔Composed of:
-Follicular Phase
-Ovulatory Phase
-Luteal Phase


Follicular Phase - correct answer ✔-begins the first day of menstruation and
lasts 12-14 days
-graafian follicle matures under the influence of luteinizing hormone (LH) &
follicle-stimulating hormone (FSH)
-maturing graafian follicle produces estrogen


Ovulatory Phase - correct answer ✔-begins when estrogen levels peak and
ends with the release of the oocyte (egg) from the mature graafian follicle
-release of the oocyte is called "ovulation"
-before this surge, estrogen levels decrease and progesterone levels increase

, Luteal Phase - correct answer ✔-begins after ovulation and lasts about 14
days
-cells of the empty follicle morph to form the corpus luteum, which produces
high levels of progesterone and low levels of estrogen
-if pregnancy occurs: corpus luteum releases progesterone and estrogen until
the placenta matures enough to assume this function
-if pregnancy does not occur: corpus luteum degenerates, resulting in a
decrease in progesterone and the beginning of menstruation


Endometrial Cycle - correct answer ✔Composed of:
-Proliferative Phase
-Secretory Phase
-Menstrual Phase


Proliferative Phase - correct answer ✔-occurs following menstruation and
ends with ovulation
-the endometrium prepares for implantation by becoming thicker and more
vascular
-these changes are in response to the increasing levels of estrogen produced
by the graafian follicle


Secretory Phase - correct answer ✔-begins after ovulation and ends with the
onset of menstruation
-the endometrium continues to thicken
-primary hormone during this phase is progesterone secreted from the corpus
luteum
-if pregnancy occurs: the endometrium continues to develop and begins to
secrete glycogen (energy source for blastocyst during implantation)
-if pregnancy does not occur: corpus luteum begins to degrade and the
endometrial tissue degenerates
