Where do sperm cells attain fertilization competence and motility?
Correct Answer: B
Rationale: The correct answer is B: epididymis. Sperm cells attain fertilization competence and motility in the epididymis. Here's the rationale:
1. Sperm cells are produced in the seminiferous tubules of the testes.
2. They then move to the epididymis for maturation, where they gain motility and the ability to fertilize an egg.
3. The epididymis provides the ideal environment for sperm to undergo final maturation processes.
4. The rete testis is a network of tubules where sperm are transported from the seminiferous tubules, not where they gain fertilization competence.
5. The vas deferens is a duct that carries sperm from the epididymis to the urethra, not where sperm attain fertilization competence.
