Nervous System & Endocrine System
Nervous System: Sending messages fast but they don’t last long
–Like an energy drink that gives you a quick burst of energy that doesn’t last very long.
Endocrine System: Sending messages slowly but they last a long time
– Like eating well, exercising and getting enough sleep will give you energy all day!
The Nervous System:Sends messages quickly but they don’t last long.
Broken into two parts:
• Central Nervous System (CNS)– Brain and spinal cord
• Peripheral Nervous System (PNS)– Carries messages to and from CNS
Central nervous system
Peripheral nervous system
The Nervous System: It breaks down into two parts.
Sympathetic and parasympathetic divisions of the nervous system
Summary of autonomic differences
Autonomic nervous system controls physiological arousal
Sympatheticdivision (arousing)
Parasympatheticdivision (calming)
Pupils dilate EYES Pupils contract
Decreases SALIVATION Increases
Perspires SKIN Dries
Increases RESPERATION Decreases
Accelerates HEART Slows
Inhibits DIGESTION Activates
Secrete stresshormones
ADRENALGLANDS
Decrease secretionof stress hormones
Endocrine SystemUses hormones that travel through the bloodstream. Takes
longer to get there but lasts a long time
The ReflexWorks by bypassing the brain so you can react quicker.
