Answer

To solve the question regarding the incorrect statement about the female reproductive system, we will analyze each option provided.

### Step-by-Step Solution:

1. **Understanding the Female Reproductive System**:
- The female reproductive system consists of primary sex organs (ovaries) and accessory ducts (oviducts, uterus, and vagina).
- Ovaries produce female gametes (eggs) and hormones.

**Hint**: Remember the distinction between primary and accessory reproductive organs.

2. **Evaluating the Statements**:
- **Statement 1**: "The oviducts (fallopian tubes) are approximately 10 to 15 cm in length and are used for conduction of the female gamete."
- This statement is **correct**. The oviducts do transport the female gamete and are indeed around this length.

**Hint**: The oviducts play a crucial role in gamete transport.

3. **Analyzing Statement 2**:
- "The narrowest part of the oviduct is the ampulla."
- This statement is **incorrect**. The ampulla is actually the widest part of the oviduct and is the site of fertilization.

**Hint**: Remember that the term "ampulla" refers to the widest part in biological contexts.

4. **Checking Statement 3**:
- "The uterus opens into the vagina through a narrow cervix."
- This statement is **correct**. The cervix is indeed narrow and connects the uterus to the vagina.

**Hint**: The cervix serves as a passage between the uterus and vagina.

5. **Reviewing Statement 4**:
- "Mons pubis is the cushion of fatty tissue covered by skin and pubic hair."
- This statement is also **correct**. The mons pubis is a fatty tissue area covered by skin and pubic hair.

**Hint**: The mons pubis is part of the external female genitalia.

6. **Conclusion**:
- After evaluating all statements, the only incorrect statement is **Statement 2**. Therefore, the answer to the question is that the incorrect statement regarding the female reproductive system is the one that states the narrowest part of the oviduct is the ampulla.

### Final Answer:
The incorrect statement regarding the female reproductive system is: "The narrowest part of the oviduct is ampulla."
