Experiment Results
Predict Question:
Predict Question 1: How will the conduction velocity in the B fiber compare with that in the A Fiber? Your answer : b. The conduction velocity in the B fiber will be slower because the B fiber has a smaller diameter and less myelination.

Predict Question 2: How will the conduction velocity in the C fiber compare with that in the B Fiber? Your answer : d. The conduction velocity will be the same in both fibers. Stop & Think Questions:

3. Note the difference in time between the action potential recorded at R1 and the action potential recorded at R2. The distance between these sets of recording electrodes is 10 centimeters (0.1 m). Convert the time from milliseconds to seconds, enter the time (in seconds) in the field below, and then click Submit to display your results in the grid.

You answered: 0.002 sec
4. Calculate the conduction velocity in meters/second by dividing the distance between R1 and R2 (0.1 m) by the time it took for the action potential to travel from R1 to R2.
Enter the conduction velocity in the field below and then click Submit to display your results in the grid. You answered: 50 m/sec
7. Note the difference in time between the action potential recorded at R1 and the action potential recorded at R2. Convert the time from milliseconds to seconds, enter the time (in seconds) in the field below, and then click Submit to display your results in the grid.
