2. CRANIAL NERVES Fig. 1.4.2

3. Autonomic Nervous System Sympathetic and Parasympathetic Divisions are shown. Sympathetic: Promotes energy expenditure, activated by emotion and stress (e.g. increases heart rate, blood pressure) Parasympathetic: Promotes digestion and excretion (e.g., stimulates salivation, stomach and intestinal activity); can be activated by severe stress Fig. 1.4.3
