How is the nervous system organized? CNS vs. PNS

CNS

• Central Nervous System

• Brain and spinal cord

• Encased in bone (why?)

• Higher functions: intelligence, emotion, memory... you!

PNS

• Peripheral Nervous System

• Everything else: nerves outside of CNS

Autonomic vs. Somatic• Autonomic Nervous System (ANS): part of the PNS that controls

involuntary functions i.e. you can’t control it– ex. heart rate, digestion, breathing, salivation– Sounds like automatic– Also called visceral nervous system– Uses smooth and cardiac muscle

• Somatic Nervous System (SoNS): part of PNS that controls voluntary functions i.e. you can control– Ex. Raise your hand– Uses skeletal muscles

- PNS

 

 

- Autonomic NS

 

 

- Work together to maintain homeostasis

 

 

Reaction to stress

 

 

Ex. heart rate/breathing up

Ex. heart rate decreases, increase digestion
