EQ1.3 Autonomic nervous system

EQ1.3 Fight or Flight Response

by Kyla Luksic

​Autonomic nervous system (ANS)

Part of nervous system responsible for many functions in the body that occur "automatically"

​

The actions of the ANS take place completely beyond our conscious control.

​

​Examples: digestion, heart rate, blood pressure, and body temperature.

​Sympathetic nervous system (SNS)

​The part of the autonomic nervous system that responds to stressful situations by initiating the fight-or-flight response.

​Parasympathetic nervous system (PNS)

​The part of the autonomic nervous system that slows down body functions, activated when you relax or when SNS stimulated too long. Also called "rest and digest".

Multiple Choice

Multiple Choice

 Division of the Autonomic Nervous System (which is a subdivision of the Peripheral Nervous System) that is & REST AND DIGEST

• sympathetic

Multiple Choice

creates a "mass alert" to cause changes throughout the body simultaneously

• Sympathetic

Multiple Choice

You're giving a speech in front of the class (most of you would feel this)

• sympathetic
• parasympathetic

Multiple Choice

Feeling of calm

• sympathetic
• parasympathetic

​Comparing the two systems

​When the sympathetic nervous system is engaged, your body is entirely focused on what will help you either fight or run away quickly.

​

​Some body functions will change to better help you in the fight or flight response.

​

​Other functions of your body that are not immediately needed stop or slow way down.
