Final answer:
The sexual response is regulated by both the sympathetic and parasympathetic divisions of the autonomic nervous system. The sympathetic division prepares the body for sexual activity, while the parasympathetic division is responsible for the engorgement of the erectile tissues and dilation of blood vessels in the reproductive organs.
Step-by-step explanation:
The sexual response is regulated by both the sympathetic and parasympathetic divisions of the autonomic nervous system. During sexual arousal, the sympathetic division prepares the body for sexual activity by increasing heart rate, blood flow to erectile tissues, and the release of vaginal secretions. On the other hand, the parasympathetic division is responsible for the engorgement of the erectile tissues and the dilation of blood vessels in the reproductive organs.
