10 Questions
Which method is used to measure the velocity of action potential in motor nerves?
Stimuli are applied at two locations and the time from stimulus to recording the nerve signal is measured.
Which equation is used to calculate the velocity of the action potential?
v = x/t
What is the distance between points 1 and 2 in the measurement of the velocity of action potential?
0.25 m
What is the time required for the nerve signal to travel the distance between points 1 and 2?
0.004 s
What is the nerve conduction velocity in the given scenario?
62.5 m/s
Which type of nerves are used for the measurement of conduction velocity?
Sensory nerves
What is the typical range of conduction velocities for sensory nerves?
40 to 60 m/s
What is the formula used to calculate the conduction velocity of the action potential?
m/s (s)t (m)x = v
What is the conduction velocity from electrode 1 to electrode 2 in the given scenario?
58 m/s
What would a conduction velocity below 10 m/s indicate?
Nerve damage
