Female Physiology Lecture Flashcards
The _______ phase describes what is happening at the OVARY from the first day of of the appearance of menses, up until ovulation (variable in length; averages 10 to 16 days).
Follicular
During the _____ phase, a cohort of new antral follicles will be recruited from the ovary and begin to proliferate (under the influence of rising plasma FSH levels).
Follicular
During the follicular phase, one of these antral follicles will be selected from this cohort to become the Graafian follicle of that cycle, which will ovulate at….
Midcycle
The ______ phase occurs at the same time as the follicular phase, but describes what is happening in the UTERUS from the first day of of the appearance of menses, up until ovulation.
Proliferative
During the _______ phase, the uterus is under the influence of increasing levels of estrogen, and the stratum functionalis (endometrial layer closest to the lumen) proliferates from 1-2 mm up to 8 to 10 mm in thickness. The endometrial glands and spiral arteries elongate along with the stratum functionalis.
Proliferative
_______ also promotes the synthesis of progesterone receptors in the uterus, so it can respond to progesterone in the post-ovulatory phase of the cycle.
Estrogen
About midway though the menstrual cycle, the antral follicle that was selected to become the Graafian follicle during the follicular phase of the cycle ruptures in response to an mid-cycle FSH / LH surge, and the oocyte is extruded from the follicle, into the fallopian tube.
Ovulation
The oocyte is viable for approximately _____ hours. If viable sperm are present in the female reproductive tract during this time, fertilization may occur (typically at the ampullary-isthmus junction of the fallopian tube).
24 hours
The _____ phase of the menstrual cycle describes what is happening in the OVARY after ovulation until the onset of the next menses (assuming pregnancy does not occur).
Luteal
The corpus luteum (formerly the Graafian follicle) is functional in the luteal phase, and this phase is therefore characterized by rising levels of _________
Progesterone
This phase is less variable in terms of it’s length (13 to 15 days) compared to the follicular phase.
