Mesonephros a temporary excretory organ in higher vertebrates is also referred as
Mesonephros a temporary excretory organ in higher vertebrates is also referred as
Show Hint
Always associate the prefix "mesonephric" with "Wolffian" (embryonic male/urinary structures) and "paramesonephric" with "Müllerian" (embryonic female reproductive structures).

- Wolffian body
- Mammilary body
- Geniculate body
- Mullerian body
Show Solution
Verified By Collegedunia
The Correct Option is A
Solution and Explanation
Step 1: Understanding the Concept:
During the embryonic development of vertebrates, three successive excretory systems develop in a cranio-caudal sequence: the pronephros, mesonephros, and metanephros.
Step 2: Detailed Explanation:
Let us review the terminology of these embryonic kidney structures:
- The mesonephros is a functional, temporary excretory organ in bird and mammalian embryos. It is commonly referred to as the Wolffian body (and its duct is the Wolffian duct).
- The Müllerian duct (or paramesonephric duct) is the embryonic precursor to the female reproductive tract (uterus, cervix, fallopian tubes).
- The mammillary body and geniculate bodies are neurological structures located in the brain.
Therefore, the mesonephros is also referred to as the Wolffian body.
Step 3: Final Answer
The correct option is (A).
