What are the different phases of menstrual cycle?

Explanation

**Step-by-Step Solution:**

1. **Understanding the Menstrual Cycle**: The menstrual cycle is a recurring process that occurs in females, typically every 28 days. It involves various physiological changes in the reproductive system.

2. **Identifying the Phases**: The menstrual cycle consists of four distinct phases:

- **Follicular Phase**: Following menstruation, this phase involves the maturation of follicles in the ovaries. The pituitary gland releases Follicle Stimulating Hormone (FSH), which stimulates the growth of ovarian follicles.
- **Ovulatory Phase**: This is the third phase where ovulation occurs. A mature ovum is released from the ovary, usually around the midpoint of the cycle. This is triggered by a surge in Luteinizing Hormone (LH).
