Identify the odd one from the following

Options

A. Labia minora
B. Fimbriae
C. Infundibulum
D. Isthmus

Answer

**Step-by-Step Solution:**

1. **Identify the Options:**
The options provided are:
- A) Labia Minora
- B) Fimbri
- C) Infundibulum
- D) Isthmus

2. **Classify Each Option:**
- **Labia Minora:** This is a part of the vulva, which is the external structure of the female reproductive system.
- **Fimbri:** This refers to the finger-like projections at the end of the fallopian tubes that help in collecting the ovum from the ovary.
- **Infundibulum:** This is the funnel-shaped opening of the fallopian tube that directs the ovum into the tube.
- **Isthmus:** This is the narrow part of the fallopian tube that connects to the uterus.

3. **Determine the Commonality:**
- The labia minora is part of the external genitalia (vulva), while fimbri, infundibulum, and isthmus are all components of the internal reproductive system (specifically the fallopian tubes).

4. **Identify the Odd One Out:**
Since labia minora is the only structure that is part of the vulva (external), while the other three (fimbri, infundibulum, isthmus) are parts of the fallopian tubes (internal), the odd one out is:
- **Labia Minora (Option A)**

5. **Conclusion:**
Therefore, the answer to the question "Identify the odd one from the following" is **Labia Minora**.
