The correct Answer is:
To answer the question: "Parasympathetic and sympathetic nerves .........., to bring about minor adjustments in internal organ activity," we need to analyze the functions of the parasympathetic and sympathetic nervous systems. ### Step-by-Step Solution: 1. **Understanding the Nervous Systems**: - The autonomic nervous system is divided into two main parts: the sympathetic and parasympathetic nervous systems. - The sympathetic nervous system is often referred to as the "fight or flight" system, which prepares the body for stressful situations. - The parasympathetic nervous system is known as the "rest and digest" system, which conserves energy and promotes maintenance activities. 2. **Function of the Sympathetic Nervous System**: - When activated, the sympathetic nervous system increases heart rate, dilates airways, and inhibits digestion. This prepares the body for rapid responses to threats. 3. **Function of the Parasympathetic Nervous System**: - In contrast, the parasympathetic nervous system decreases heart rate, constricts airways, and stimulates digestion. This promotes a state of calm and conserves energy. 4. **Antagonistic Action**: - The two systems often have opposing effects on the same organs. For example, while the sympathetic system increases heart rate, the parasympathetic system decreases it. This antagonistic relationship allows for fine-tuning of bodily functions. 5. **Conclusion**: - Given that both systems work in opposition to each other to regulate internal organ activity, the correct completion of the statement is: "Parasympathetic and sympathetic nerves work antagonistically, to bring about minor adjustments in internal organ activity." ### Final Answer: Parasympathetic and sympathetic nerves **work antagonistically**, to bring about minor adjustments in internal organ activity. ---
