A 45-year-old diabetic male is experiencing erectile dysfunction. If his erectile dysfunction is caused by the nervous system, then the nurse can educate the client that the venous blood supply to the penis is controlled by:
- A. sympathetic nerves.
- B. parasympathetic nerves.
- C. somatic nerves.
- D. spinal reflexes.
Correct Answer: B
Rationale: Erectile function is primarily controlled by the parasympathetic nervous system, which facilitates the dilation of blood vessels in the penis. The parasympathetic nerves are responsible for vasodilation in the penis, allowing blood to enter and creating an erection. Sympathetic nerves, on the other hand, are responsible for ejaculation by causing contraction of the muscles around the vas deferens. Somatic nerves are involved in sensation and movement, not specifically in controlling blood supply to the penis. Spinal reflexes can play a role in the erectile process, but they are not directly responsible for controlling the venous blood supply.
