subtractive technique that uses nerve stimulation at two points and subtracting the difference between the two recorded latencies (time from stimulation to muscle contraction) gives a more accurate estimate of motor conduction velocity than stimulating the nerve at one point and measuring the time it takes for the muscle to contract. Which of the following statements best describes the reason why the subtractive techniques is more accurate? The subtractive technique is more accurate because it takes into account the delay caused by the electrical resistance of the

Which of the following statements best describes the reason why the subtractive techniques is more accurate?
|
The subtractive technique is more accurate because it takes into account the delay caused by the electrical resistance of the recording electrodes, which adds to the recorded delay. |
||
|
The subtractive technique is more accurate because it takes into account the delay caused by synaptic transmission from the axon terminals to the muscle fibres. |
||
|
The subtractive technique is more accurate because it takes into account the slower conduction speed of the small unmyelinated axon endings that slow down nerve conduction before the action potential reaches the muscle fibre. |
