1. THE NERVOUS SYSTEM An Introduction

2. Basic Functions  Sensory Input  Integration  Motor Output

3. Nervous vs. Endocrine Fast Control Neurons Neurotransmitters Short-Term Effects “Slow” Control Blood Stream Hormones Lasting Effects Monitor Stimuli React Homeostasis

4. Nervous System Central Nervous System Peripheral Nervous System Somatic Autonomic Sympathetic Parasympathetic Sensory (afferent) Motor (efferent)

5. Organization of the Nervous System 1. Central Nervous System (CNS)  Brain, Spinal Cord  Integration Center 2. Peripheral Nervous System (PNS)  Nerves  Sensation, Reaction

6.  Sensory (Afferent)  Sense Receptors  CNS  Monitors interior & exterior  Motor (Efferent)  CNS  Effectors (Muscles/Glands) Organization of the PNS

7. Organization of the Efferent Division 1. Somatic  Voluntary  CNS  Skeletal Muscles 2. Autonomic  Involuntary  CNS  Glands, cardiac, smooth muscle

8. Autonomic Organization  Sympathetic  “Fight or Flight”  Parasympathetic  “Rest or Digest”
