Action potential

Question 1

What are the steps of an action potential

Answer 1

Step 1: The resting state
Step 2: Depolarisation 
Step 3: Repolarisation 
Step 4: Hyperpolarisation
Step

Question 2

The action potential

Answer 2

If a stimulation that travels through the neuron is strong enough, the signal will continue through the axon of the neuron and this is what is the action potential. When this happens, the neuron fires.

Question 3

Refer to the picture, and outline the steps.

Answer 3

Step 1 - Resting state
Step 2- Stimulus initiates Depolarisation with Na+ in
Step 3 - Repolarisation k+ out
Step 4 - Hyperpolarisation 
Returns to resting state

Question 4

What is the resting potential mV?

Answer 4

-70

Question 5
