Question

Match List-I with List-II: 

List-I (Remnant structure)	List-II (Duct part forming it)
(A) Epoophoron	(I) Mesonephric tubule cranial to developing gonads
(B) Paraoophoron	(II) Mesonephric tubule caudal to developing gonads
(C) Gartner's duct	(III) Paramesonephric duct
(D) Uterus masculinus	(IV) Mesonephric duct

Choose the correct answer from the options given below:

• (A) - (I), (B) - (II), (C) - (III), (D) - (IV)
• (A) - (II), (B) - (I), (C) - (III), (D) - (IV)
• (A) - (I), (B) - (II), (C) - (IV), (D) - (III)
• (A) - (II), (B) - (I), (C) - (IV), (D) - (III)

Hint:

To remember reproductive remnants:
- Müllerian (Paramesonephric) remnants in males \(\rightarrow\) Uterus masculinus.
- Wolffian (Mesonephric) remnants in females \(\rightarrow\) Epoophoron, Paraoophoron, and Gartner's duct.

Answer 1

The Correct Option is C

Step 1: Understanding the Concept:
During embryonic development, the reproductive tract forms from two sets of paired ducts: the mesonephric (Wolffian) ducts and the paramesonephric (Müllerian) ducts.
One set of ducts regresses depending on the genetic sex of the embryo, leaving behind vestigial vestigial remnants in the adult animal.

Step 2: Detailed Explanation:
Let us match each vestigial remnant with its embryological origin:
- (A) Epoophoron: This is a vestigial structure found in the broad ligament near the ovary. It is composed of remnants of the cranial mesonephric tubules (I). Thus, (A) matches with (I).
- (B) Paraoophoron: This is a similar remnant located closer to the uterus, composed of the caudal mesonephric tubules (II). Thus, (B) matches with (II).
- (C) Gartner's duct: This is a vestigial cystic structure located in the lateral wall of the vagina. It is a remnant of the main mesonephric duct (IV) in females. Thus, (C) matches with (IV).
- (D) Uterus masculinus (Prostatic utricle): This is a small, blind pouch located in the male prostate gland. It is a remnant of the paramesonephric duct (III), which normally develops into the uterus and fallopian tubes in females. Thus, (D) matches with (III).
This matching sequence gives: (A) - (I), (B) - (II), (C) - (IV), (D) - (III).

Step 3: Final Answer:
The correct match is (A) - (I), (B) - (II), (C) - (IV), (D) - (III). This corresponds to option (C).
