Ovarian Cycle, pg 958 - 959
• The monthly series of events associated with the
maturation of an egg is call the _____ ______.
• Repeats every 28 days with _______ occuring
mid-cycle 1 .Triggered by LH hormone.
• 2 consecutive phases
1. ________ phase – time of follicle growth (1 –
14th day of menstrual cycle)
2. _______ phase – time of corpus luteum activity
(days 14 – 28 of menstrual cycle)
1 = ovulation is the release of an egg

NOTE: 1 – 6 shows
progession of follicle
development with egg; 7
is ovulation
And, steps 1-7 represent
the follicular phase
Steps 8-9 represent the
luteal phase
Corpeus luteum

to produce estrogen.
• Days 6 – 14 – uterine ling
________ itself. Estrogen
levels ______. Ovulation takes
place on day 14 due to sudden
release of LH from anterior
pituitary gland.
