Which of the following structure is incorrectly paired with its function :-

Options

A. Seminal vesicle - Secrete sugar containing fluid
B. Fimbriae - Help in collection of the ovum after ovulation
C. Ovary - Secrete steroid hormone
D. Bartholin gland - destroy the acidity of urethra

Answer

To solve the question regarding which structure is incorrectly paired with its function, we will analyze each option provided in the question step by step.

### Step 1: Analyze the Seminal Vesicle
- **Function**: The seminal vesicle is responsible for secreting fructose, enzymes, nutrients, calcium, and prostaglandins.
- **Conclusion**: This pairing is correct as the seminal vesicle is known to contribute approximately 60% of the volume of seminal fluid.

**Hint**: Remember that the seminal vesicle plays a crucial role in providing energy (fructose) for sperm.

### Step 2: Analyze the Fimbriae
- **Function**: Fimbriae are small, finger-like projections that help collect the ovum after ovulation.
- **Conclusion**: This pairing is also correct, as fimbriae are indeed part of the infundibulum of the fallopian tube and assist in capturing the ovum.

**Hint**: Think of fimbriae as the "catchers" of the ovum during ovulation.

### Step 3: Analyze the Ovary
- **Function**: The ovary secretes steroidal hormones, specifically estrogens and progesterone.
- **Conclusion**: This pairing is correct, as these hormones are essential for the regulation of the menstrual cycle and reproductive functions.

**Hint**: Recall the importance of estrogen and progesterone in female reproductive health.

### Step 4: Analyze the Bartholin's Gland
- **Function**: The statement claims that Bartholin's gland destroys the acidity of the urethra.
- **Conclusion**: This pairing is incorrect. Bartholin's glands (or greater vestibular glands) are responsible for secreting a viscous fluid that aids in lubrication during sexual intercourse, not for altering the acidity of the urethra.

**Hint**: Remember that Bartholin's glands are more about lubrication than pH balance.

### Final Conclusion
After analyzing all the structures and their functions, we find that the incorrect pairing is related to the Bartholin's gland. Therefore, the answer to the question is:

**Answer**: The structure incorrectly paired with its function is the Bartholin's gland.
