27
Q

Put these in order: Refractory period, resting potential, action potential

A

Resting potential, action potential, refractory period

28
Q

Describe resting potential

A

The neuron has potential to fire

29
Q

What stage do the neurons dock at each other

A

Resting potential

30
Q

What happens after neurons dock

A

The message is sent to the soma

31
Q

Where does action potential happen

A

The axon

32
Q

Once the message reaches the terminal buttons, what happens to the axon

A

It returns to its previous state of slightly negative

33
Q

What is the role of the myelin sheath in action potential

A

Accelerates transmission of neural impulses, acts as insulation

34
Q

True or False: neurotransmitters either dock at the proper receptor site or remain in the synapse

A

True

35
Q

The resetting of the neurotransmitters and the return of the axon to slightly negative in the interior to slightly positive in the exterior

A

Refractory period

36
Q

Summarize neuron firing

A

Terminals dock with dendrites, once the message is received in the soma, action potential starts in the axon, the myelin sheath speeds up the message, the terminals relay the message to the next set, everything resets in the refractory period
