Final answer:
The event that does not describe the follicular phase of the ovarian cycle is c) Ovulation. The follicular phase involves the development of a mature follicle and increases in FSH and estrogen levels. Ovulation marks the end of the follicular phase and the beginning of the luteal phase.
Step-by-step explanation:
Which of the following does not describe events of the follicular phase of the ovarian cycle? The correct answer is c) Ovulation. During the follicular phase, a mature follicle develops due to an increase in follicle-stimulating hormone (FSH) levels, and estrogen levels rise as the follicle produces more estrogen. However, ovulation, which is the release of the mature egg from the follicle, does not occur until the end of the follicular phase and is triggered by a surge in luteinizing hormone (LH) due to the previously elevated estrogen levels. This typically happens around day 14 of a 28-day cycle, thus marking the transition to the next phase, the luteal phase, where progesterone is released by the corpus luteum after ovulation.
