1 Anatomy and Physiology for Emergency Care Chapter 9 The Peripheral Nervous System and Integrated Neural Functions

2 Objectives Identify the cranial nerves, and relate each pair of cranial nerves to its principle functions Identify the cranial nerves, and relate each pair of cranial nerves to its principle functions Relate the distribution pattern of spinal nerves to the regions they innervate Relate the distribution pattern of spinal nerves to the regions they innervate Distinguish between the motor responses produced by simple and complex reflexes Distinguish between the motor responses produced by simple and complex reflexes Explain how higher centers control and modify reflex responses Explain how higher centers control and modify reflex responses

3 Objectives Identify the principle sensory and motor pathways Identify the principle sensory and motor pathways Explain how we can distinguish among sensations from different areas of the body Explain how we can distinguish among sensations from different areas of the body Compare the ANS with other divisions of the nervous system Compare the ANS with other divisions of the nervous system Explain the functions and structures of the sympathetic and parasympathetic divisions Explain the functions and structures of the sympathetic and parasympathetic divisions

4 Objectives Discuss the relationship between the sympathetic and parasympathetic divisions, and explain the implications of dual innervation Discuss the relationship between the sympathetic and parasympathetic divisions, and explain the implications of dual innervation Discuss the interrelationships among the nervous system and other organ systems Discuss the interrelationships among the nervous system and other organ systems
