The nurse is explaining the function of the male’s cremaster muscle to a group of nursing students. Which statement accurately describes the function of the cremaster muscle?
- A. Assists with transporting sperm
- B. Aids in temperature control of the testicles
- C. Aids in voluntary control of excretion of urine
- D. Entraps blood in the penis to produce an erection
Correct Answer: B
Rationale: The correct answer is B: Aids in temperature control of the testicles. The cremaster muscle contracts in response to cold temperatures to pull the testicles closer to the body for warmth, and relaxes in warm temperatures to move the testicles away for cooling. This mechanism helps regulate the temperature required for optimal sperm production.
Explanation of why the other choices are incorrect:
A: The cremaster muscle is not directly involved in transporting sperm.
C: The cremaster muscle is not related to the control of urine excretion.
D: The cremaster muscle does not play a role in trapping blood in the penis for an erection.
