Anatomy and Physiology for Emergency Care

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
• Relate the distribution pattern of spinal nerves
  to the regions they innervate
• Distinguish between the motor responses produced
  by simple and complex reflexes
• Explain how higher centers control and modify
  reflex responses

3
Objectives

• Identify the principle sensory and motor pathways
• Explain how we can distinguish among sensations
  from different areas of the body
• Compare the ANS with other divisions of the
  nervous system
• 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 interrelationships among the nervous
  system and other organ systems
