During which cycle day of a typical 28 day menstrual cycle does the follicular phase
occur?
A. Cycle days 7-14
B. Cycle days 14-28
C. Cycle days 1-6
D. Cycle days 1-13 - Answer D. Cycle days 1-13
As the graafian follicle matures, a massive amount of estrogen is released by the follicle
which causes a luteinizing hormone surge. Approximately, what cycle day does the LH
surge occur?
A. Cycle day 11-13
B. Cycle day 14
C. Cycle day 5-8
D. Cycle day 1-6 - Answer A. Cycle day 11-13
Select all the functions of the luteinizing hormone:
A. Forming the corpus luteum
B. Thickening the endometrium layer for implantation
C. Breaking down the wall of the graffian follicle to allow for release of the ovum
D. Thinning cervical mucous - Answer A and C
During which stage of the menstrual cycle does the endometrium layer thicken?
, A. Secretory Phase
B. Luteal Phase
C. Ovulation Phase
D. Proliferative Phase - Answer The answer is D. The proliferative phase is where the
endometrium layer is rebuilding. Remember during the menstrual phase (cycle days 1-6)
the endometrium layer sheds and must be rebuilt. The estrogen released from the
follicle (as it matures) causes the endometrium to thicken, in case pregnancy occurs
during this cycle.
What cycle day does the proliferative stage occur?
A. Cycle day 7-14
B. Cycle day 14-28
C. Cycle day 1-6
D. Cycle day 1-14 - Answer The answer is A. The proliferative phase is where the
endometrium starts to thicken. It occurs cycle days 7-14. Remember in cycle days 1-6
(the menstrual phase) the endometrium layer sheds. Now the endometrium must be
rebuilt in case pregnancy occurs. Estrogen is responsible for rebuilding the
endometrium.
Which statement is TRUE about the ovulation phase?
A. The newly released egg will live for 72 hours and disintegrate if not fertilized.
B. The woman will have a low basal body temperature before ovulation and then a
temperature increase of 0.4-1'F degrees around ovulation.
C. The ovum is directly released into the fallopian tube.
D. Fertilization most commonly occurs at the fimbria. - Answer The answer is B. Option
B is the only correct statement. Option A is wrong because the newly released egg will
live for 24 hours (NOT 72) and disintegrate if not fertilized. Option C is wrong because
the ovum is directly released into the peritoneal cavity (not fallopian tube) and THEN
enters into the fallopian tube with the help of the fimbrae which have cilia that help
sweep the ovum into the fallopian tube. Option D is wrong because fertilization most
commonly occurs in the AMPULLA of the fallopian tube (not fimbria).
If the ovum is to be fertilized, where is the most common site of fertilization?
A. Uterine wall
B. Fimbria
C. Ampulla of the Fallopian Tube
