Question

Select the correct route for the passage of sperms in male frogs :

• A. Testes $\rightarrow$ Vasa efferentia $\rightarrow$ Kidney $\rightarrow$ Seminal Vesicle $\rightarrow$ Urinogenital duct $\rightarrow$ Cloaca
• B. Testes $\rightarrow$ Vasa efferentia $\rightarrow$ Bidder's canal $\rightarrow$ Ureter $\rightarrow$ Cloaca
• C. Testes $\rightarrow$ Vasa efferentia $\rightarrow$ Kidney $\rightarrow$ Bidder's canal $\rightarrow$ Urinogenital duct $\rightarrow$ Cloaca
• D. Testes $\rightarrow$ Bidder's canal $\rightarrow$ Kidney $\rightarrow$ Vasa efferentia $\rightarrow$ Urinogenital duct $\rightarrow$ Cloaca

Answer 1

The Correct Option is C

The question asks about the correct passage of sperms in male frogs. To answer this, we need to understand the anatomical pathway sperms take in the reproductive system of a male frog.

In male frogs, sperms are produced in the testes and need to be transported towards the cloaca for eventual release. Here's the correct route for the passage of sperms:

1. Testes: This is where sperms are produced.
2. Vasa efferentia: These ducts transport sperms from the testes to the kidneys.
3. Kidney: In frogs, unlike mammals, the kidneys play a role in the transport of sperms due to the amphibian excretory system.
4. Bidder's canal: This channel runs alongside the kidney and is involved in the transport of sperms.
5. Urinogenital duct: This duct carries both urine and sperms towards the cloaca.
6. Cloaca: This is the common chamber where excretory and reproductive tracts open, allowing for the release of sperms to the external environment.

Based on the explanation above, the correct route is:

Testes $\rightarrow$ Vasa efferentia $\rightarrow$ Kidney $\rightarrow$ Bidder's canal $\rightarrow$ Urinogenital duct $\rightarrow$ Cloaca

In the given options, this matches the third option:

• Testes $\rightarrow$ Vasa efferentia $\rightarrow$ Kidney $\rightarrow$ Bidder's canal $\rightarrow$ Urinogenital duct $\rightarrow$ Cloaca
