Divisions of Nervous System and Neural Pathways
Nervous System
CNS
Spinal cord and brain
PNS
Nerve cells that carry information to and/or from the CNS
Somatic (SNS)
Voluntary movement of skeletal movement
Autonomic (ANS)
Involuntary control of smooth muscles
Sympathetic
Increases breathing and heart rate
Decreases peristalsis and intestinal secretions
Parasympathetic
Decreases breathing and heart rate
Increases peristalsis and intestinal secretions
How the Nervous System Works
Receptors respond to stimulus and produce electric impulses in response
Effectors produce a response to a detected stimulus
ANS
Antagonistic systems
Parasympathetic
"rest and digest"
Sympathetic
"fight or flight"
