1. **Stating the problem:** Differentiate between the sympathetic and parasympathetic nervous systems and write the functions of each. 2. **Understanding the systems:** The autonomic nervous system has two main divisions: sympathetic and parasympathetic. 3. **Differences:** - Sympathetic nervous system prepares the body for 'fight or flight' responses. - Parasympathetic nervous system promotes 'rest and digest' activities. 4. **Functions of Sympathetic Nervous System:** - Increases heart rate and blood pressure. - Dilates pupils. - Inhibits digestion. - Stimulates release of glucose for energy. 5. **Functions of Parasympathetic Nervous System:** - Decreases heart rate. - Constricts pupils. - Stimulates digestion and absorption. - Promotes energy storage. 6. **Summary:** The sympathetic system activates the body for action, while the parasympathetic system conserves energy and maintains homeostasis.
