Final answer:
The two divisions of the autonomic nervous system, the sympathetic and parasympathetic divisions, interact in various ways, including counterbalancing each other, working together, or acting alone on specific organs. They can also have opposite effects on the function of an organ.
Step-by-step explanation:
The two divisions of the autonomic nervous system, namely the sympathetic and parasympathetic divisions, interact in multiple ways:
One division may counterbalance the other division: The sympathetic division prepares the body for stress-related activities, while the parasympathetic division returns the body to routine operations. They work together to maintain homeostasis.
Occasionally only one division communicates with an organ: In some cases, only one division of the autonomic nervous system is involved in regulating the activity of a specific organ.
Both divisions may work together for the function of an organ or a process: In certain situations, the sympathetic and parasympathetic divisions cooperate to achieve a specific function in an organ or process.
One division may increase function of an organ, while the other division inhibits it: The sympathetic division can increase the activity of an organ, while the parasympathetic division can decrease its activity.
All of the answers mentioned (A, B, C, and D) are correct regarding the interaction between the two divisions of the autonomic nervous system.
