B. The clitoris is a tiny finger - like structure which lies at the upper junction of the two labia majora above the urethral opening.
C. Each fallopian tube is about 10 - 12 cm long and extends from the periphery of each ovary to the uterus the part closer to the ovary is the funnel - shaped infundibulum .
D. The cavity of the cervix is called cervical canal. Which along with vagina forms the birth canal.

Answer

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

### Step-by-Step Solution:

1. **Identify the Statements**:
We have several statements about the human female reproductive system that need to be evaluated for correctness.

2. **Evaluate the First Statement**:
- **Statement**: "The wall of the uterus has three layers."
- **Analysis**: This statement is correct. The uterus consists of three layers:
- Perimetrium (outer layer)
- Myometrium (middle layer)
- Endometrium (inner layer)

3. **Evaluate the Second Statement**:
- **Statement**: "The laterus is a teeny finger-like structure which lies at the upper junction of the 2 labia minora above the urethral opening."
- **Analysis**: This statement is incorrect. The correct term should be "clitoris," not "laterus." The clitoris is indeed a small, finger-like structure located at the junction of the labia minora.

4. **Evaluate the Third Statement**:
- **Statement**: "Each fallopian tube is about 10 to 12 cm long and extends from the periphery of each ovary to the uterus."
- **Analysis**: This statement is correct. The fallopian tubes (oviducts) are approximately 10 to 12 cm long and connect the ovaries to the uterus.

5. **Evaluate the Fourth Statement**:
- **Statement**: "The cavity of the cervix is called the cervical canal which along with the vagina forms the birth canal."
- **Analysis**: This statement is also correct. The cervical canal is indeed part of the birth canal along with the vagina.

6. **Conclusion**:
The incorrect statement among the given options is the second statement regarding the "laterus."

### Final Answer:
The incorrect statement is: "The laterus is a teeny finger-like structure which lies at the upper junction of the 2 labia minora above the urethral opening."
