Question

Choose the correct sequence of sperm transport during ejaculation

• A. Seminiferous tubules $\rightarrow$ vasa efferentia $\rightarrow$ rete testis $\rightarrow$ epididymis $\rightarrow$ vas deferens $\rightarrow$ ejaculatory duct
• B. Seminiferous tubules $\rightarrow$ rete testis $\rightarrow$ epididymis $\rightarrow$ vas deferens $\rightarrow$ vasa efferentia $\rightarrow$ ejaculatory duct
• C. Seminiferous tubules $\rightarrow$ rete testis $\rightarrow$ vasa efferentia $\rightarrow$ epididymis $\rightarrow$ vas deferens $\rightarrow$ ejaculatory duct
• D. Seminiferous tubules $\rightarrow$ rete testis $\rightarrow$ epididymis $\rightarrow$ vasa efferentia $\rightarrow$ vas deferens $\rightarrow$ ejaculatory duct

Hint:

Sperm travel from seminiferous tubules to ejaculatory duct via rete testis, vasa efferentia, epididymis, and vas deferens.

Answer 1

The Correct Option is C

• Sperm Transport Path: Sperm travel from production to ejaculation through a specific route in the male reproductive system.
• Sequence Analysis:
  • Sperm are produced in seminiferous tubules.
  • They move to the rete testis, a network of tubules.
  • Vasa efferentia transport sperm from rete testis to the epididymis.
  • Epididymis stores and matures sperm.
  • Vas deferens conducts sperm to the ejaculatory duct.
  • Ejaculatory duct releases sperm during ejaculation.
• Option Analysis:
  • (1) Seminiferous tubules → vasa efferentia → rete testis → epididymis → vas deferens → ejaculatory duct: Incorrect, rete testis comes before vasa efferentia.
  • (2) Seminiferous tubules → rete testis → epididymis → vas deferens → vasa efferentia → ejaculatory duct: Incorrect, vasa efferentia precedes epididymis.
  • (3) Seminiferous tubules → rete testis → vasa efferentia → epididymis → vas deferens → ejaculatory duct: Correct, follows the anatomical sequence.
  • (4) Seminiferous tubules → rete testis → epididymis → vasa efferentia → vas deferens → ejaculatory duct: Incorrect, vasa efferentia is out of order.
• Conclusion: The correct answer is (3), as it accurately represents the sperm transport sequence.
