13. The Nervous System: Sends messages quickly but they don’t last long
The Nervous System: Sends messages quickly but they don’t last long. Broken into two parts:
Central Nervous System (CNS)
Peripheral Nervous System (PNS)

14. The Nervous System: It breaks down into two parts.

20. Sympathetic and parasympathetic divisions of the nervous system
Kolb & Whishaw, An Introduction to Brain and Behavior
How is the Brain Organized? Figure 2.29
Sympathetic and parasympathetic divisions of the nervous system

21. Summary of autonomic differences
Autonomic nervous system controls physiological arousal
Sympathetic
division (arousing)
Parasympathetic
division (calming)
Pupils dilate EYES Pupils contract
Decreases SALIVATION Increases
Perspires SKIN Dries
Increases RESPERATION Decreases
Accelerates HEART Slows
Inhibits DIGESTION Activates
Secrete stress
hormones
ADRENAL
GLANDS
Decrease secretion
of stress hormones
key words: sympathetic nervous system; parasympathetic nervous system

22. Endocrine System Uses hormones that travel through the bloodstream
Endocrine System Uses hormones that travel through the bloodstream. Takes longer to get there but lasts a long time
