3.7 PEx: Neurophysiology of Nerve Impulses part 2

part A
Which fibers generate the smallest value for conduction velocity?
    C fibers
    D fibers
    B fibers
    A fibers

Part B

The time interval for conduction would be shortest with
    the smallest unmyelinated axons
    the largest and most heavily myelinated axons
    the smallest and most heavily myelinated axons
    the largest unmyelinated axons

Part C

Increasing the amount of myelination _______.
    increases the time between action potentials
    has no effect on the time between action potentials
    increases the time between action potentials only for small-diameter axons
    decreases the time between action potential

Part D
In this activity, the stimulus voltage used was _______.
    the same for all of the axons and suprathreshold for all of the axons
    the same for all of the axons
    altered to accommodate the structural differences
    suprathreshold for all of the axons
