Exercise 3: Neurophysiology of Nerve Impulses: Activity 3: The Action Potential: Threshold Lab Report
Pre-lab Quiz Results
You scored 100% by answering 4 out of 4 questions correctly.
1. Axons are
You correctly answered: d. long, thin structures that extend from a neuronal cell body.
2. Which of the following is easier?
You correctly answered: a. extracellular recordings of the action potential
3. An action potential is usually initiated in an axon at or near
You correctly answered: d. all of the above
4. The initiation of an action potential in a sensory neuron in the body normally
You correctly answered: a. follows a sufficiently large depolarizing receptor potential.


Post-lab Quiz Results
You scored 100% by answering 3 out of 3 questions correctly.
1. The threshold voltage in an axon is usually
You correctly answered: a. less negative than the resting membrane potential.
2. If a graded receptor potential made the resting membrane potential of the axon more negative (for example, -70 mV
changes to -75 mV), you would expect
You correctly answered: d. it to be more difficult for this axon to reach the threshold voltage.
3. Failure to reach the threshold voltage in the axon of a sensory neuron could be caused by
You correctly answered: d. all of the above.
