Question

while the follicular phase is occurring in the ovary, what is occurring in the uterus?
a ovulation
b menses
c proliferative phase
d both menses and proliferative phase

Explanation:

The ovarian cycle has a follicular phase. The uterine cycle has menstruation (days 1 - 5) and the proliferative phase (days 6 - 14). The follicular phase of the ovarian cycle (days 1 - 14) overlaps with both menstruation and the proliferative phase of the uterine cycle. Ovulation occurs at the end of the follicular phase (day 14), but it is an ovarian event, not a uterine one. Menses (menstruation) is part of the uterine cycle (days 1 - 5), and the proliferative phase (days 6 - 14) is also part of the uterine cycle. Since the follicular phase (days 1 - 14 in the ovary) includes the time when menses (days 1 - 5) and the proliferative phase (days 6 - 14) occur in the uterus.

Answer:

D. Both menses and proliferative phase
