In a normal 28-day menstrual cycle, the rupture of the Graafian follicle releasing the ovum takes place during which phase?

1. The menstrual cycle has four phases: menstrual, follicular, ovulatory and luteal. 2. On about the 14th day the Graafian follicle ruptures and releases the ovum. 3. This is the ovulatory phase, marked by an LH peak. 4. The menstrual phase is bleeding, the follicular phase is follicle growth, and the luteal phase forms the corpus luteum, so they are ruled out. _Source: Samacheer Kalvi (TN SCERT) Class 10 Science, Unit 17 Reproduction in Plants and Animals "Menstrual Cycle", p.258_
