Which of the following depicts the correct pathway of transport of sperms? (NEET 2016 Phase-2)
Answer: (A) Rete testis → Efferent ductules → Epididymis → Vas deferens. Answer: (A) Rete testis → Efferent ductules → Epididymis → Vas deferens Solution: Sperms made in the seminiferous tubules open into the vasa efferentia (efferent ductules) through the rete testis; the vasa efferentia open into the epididymis, which then leads to the vas deferens.
- A.Rete testis → Efferent ductules → Epididymis → Vas deferens✓
- B.Rete testis → Epididymis → Efferent ductules → Vas deferens
- C.Rete testis → Vas deferens → Efferent ductules → Epididymis
- D.Efferent ductules → Rete testis → Vas deferens → Epididymis
Correct Answer
(A) Rete testis → Efferent ductules → Epididymis → Vas deferens
Solution & Explanation
Answer: (A) Rete testis → Efferent ductules → Epididymis → Vas deferens Solution: Sperms made in the seminiferous tubules open into the vasa efferentia (efferent ductules) through the rete testis; the vasa efferentia open into the epididymis, which then leads to the vas deferens. This fixes the order as rete testis → efferent ductules → epididymis → vas deferens. NCERT Reference: Ch 2, p.27, line 42 — "the testis open into the vasa efferentia through rete testis. The vasa efferentia"
