The Three phases that occur successively during menstral cycle include

Options

A. follicular phase - ovulatory phase - luteal phase
B. follicular phase - luteal phase - ovulatory phase
C. follicular phase - menstral phase - luteal phase
D. ovulatory phase - luteal phase - follicular phase

Answer

**Step-by-Step Solution:**

1. **Understanding the Menstrual Cycle:**
The menstrual cycle consists of several phases that occur in a specific order. It typically lasts about 28 days, but can vary among individuals.

2. **Identifying the Phases:**
The three main phases of the menstrual cycle are:
- **Follicular Phase:** This is the first phase where the follicles in the ovaries mature in response to Follicle Stimulating Hormone (FSH). The uterus also prepares for potential implantation of a fertilized egg.
- **Ovulatory Phase:** This is the second phase where a surge in Luteinizing Hormone (LH) triggers ovulation, leading to the release of a mature egg from the ovary.
- **Luteal Phase:** This is the final phase that occurs after ovulation. The ruptured follicle transforms into the corpus luteum, which secretes hormones to maintain the uterine lining for a possible pregnancy.

3. **Arranging the Phases in Order:**
The correct order of the phases is:
- Follicular Phase
- Ovulatory Phase
- Luteal Phase

4. **Selecting the Correct Option:**
Based on the phases identified and their order, the correct option that lists these phases successively is:
- Follicular Phase, Ovulatory Phase, Luteal Phase.

**Final Answer:** The three phases that occur successively during the menstrual cycle are the Follicular Phase, Ovulatory Phase, and Luteal Phase.
