Read the following statements about the human female reproductive system and identify the incorrect statement.

Options

A. The wall of the uterus has three layers of tissue. The external thin membranous perimetruim , middle thick layer of smooth muscle , myometrium and inner glandular layer called endometrium that lines the uterine cavity .
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 of the provided statements step by step.

### Step 1: Analyze the First Statement
- **Statement**: "The wall of the uterus has three layers of tissue: external thin membranous perimetrium, a middle thick layer of smooth muscle myometrium, and an inner glandular layer called endometrium that lines a uterine cavity."
- **Analysis**: This statement is correct. The uterus indeed has three layers: the perimetrium (outer layer), myometrium (middle layer), and endometrium (inner layer).

**Hint**: Remember the three layers of the uterus and their functions.

### Step 2: Analyze the Second Statement
- **Statement**: "The clitoris is a tiny finger-like structure which lies at the upper junction of the two labia minora above the urethral opening."
- **Analysis**: This statement is incorrect. The clitoris is located at the upper junction of the labia minora, but it is not described accurately as a "finger-like structure." It is more of a small, erectile structure that is not specifically finger-like.

**Hint**: Consider the anatomical position of the clitoris in relation to the labia minora.

### Step 3: Analyze the Third Statement
- **Statement**: "Each fallopian tube is about 10 to 12 centimeters long and extends from the periphery of each ovary to the uterus; the part closer to the ovary is funnel-shaped (infundibulum)."
- **Analysis**: This statement is correct. The fallopian tubes do extend from the ovaries to the uterus and have a funnel-shaped structure at the end closest to the ovary called the infundibulum.

**Hint**: Recall the structure and function of the fallopian tubes.

### Step 4: Analyze the Fourth Statement
- **Statement**: "The cavity of the cervix is called the cervical canal, which along with the vagina forms a birth canal."
- **Analysis**: This statement is also correct. The cervical canal is indeed part of the birth canal along with the vagina.

**Hint**: Think about the role of the cervix and vagina during childbirth.

### Conclusion
After analyzing all the statements, the incorrect statement is the second one regarding the clitoris.

### Final Answer
The incorrect statement is the second one: "The clitoris is a tiny finger-like structure which lies at the upper junction of the two labia minora above the urethral opening."
