Which stage of meiosis is an ovulated cell in quizlet?
A secondary oocyte is formed during the day preceding ovulation in each ovarian cycle. Stimulated by the LH surge, a primary oocyte in the Graafian follicle completes meiosis I to form a haploid secondary oocyte. This secondary oocyte begins meiosis II but arrests in metaphase; this is the oocyte that is ovulated.

What event occurs during ovulation?
Ovulation is the release of eggs from the ovaries. In women, this event occurs when the ovarian follicles rupture and release the secondary oocyte ovarian cells. After ovulation, during the luteal phase, the egg will be available to be fertilized by sperm.
Where does fertilization occur?
Fertilization of an egg by a sperm normally occurs in the fallopian tubes. The fertilized egg then moves to the uterus, where it implants to the uterine lining.
Is the ovarian cycle the same as the menstrual cycle?
