What is the difference between sympathetic and parasympathetic nervous system?
The sympathetic nervous system arouses you while the parasympathetic nervous system calms you
_______________________________________________For Sympathetic, think fight or flight
Where are all of the sensory and motor neurons located?
In the peripheral nervous system (PNS)
Which nervous system does all of the muscular activity happen?

_______________________________________________Allows you to MOVE in case of emergency
What is meant by action potential?
a rapid sequence of changes in the voltage across a membrane.
What is meant by threshold?

What is a synapse?
A gap between neurons
(also called a synaptic gap or cleft)
What are neurotransmitters?

Directs messages through the cortex and replies from the Cerebellum and Medulla.
If you fell down because you lost your balance, what part of the brain would you blame it on?
