Title: Physioex 9.0 Exercise 3 pre and post quizzes Activity 3 Post by: trin on Aug 24, 2012 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.
