Question 27

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

Answer 27

Resting potential, action potential, refractory period

Question 28

Describe resting potential

Answer 28

The neuron has potential to fire

Question 29

What stage do the neurons dock at each other

Answer 29

Resting potential

Question 30

What happens after neurons dock

Answer 30

The message is sent to the soma

Question 31

Where does action potential happen

Answer 31

The axon

Question 32

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

Answer 32

It returns to its previous state of slightly negative

Question 33

What is the role of the myelin sheath in action potential

Answer 33

Accelerates transmission of neural impulses, acts as insulation

Question 34

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

Answer 34

True

Question 35

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

Answer 35

Refractory period

Question 36

Summarize neuron firing

Answer 36

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
