<prompt> Sensory nerve action potential in NCV to calculateSensory conductionMotor conductionVelocity conductionMuscular contraction  <response>: Sensory conduction 24-Apleys 8thSensory nerve conduction - If a sensory nerve is stimulated distally, the sensory nerve action potential SNAP can be recorded at a proximal site, here again, by measuring the distance between stimulating and recording electrodes and the time lapse between stimulus and response, the sensory nerve conduction velocity can be calculated.Motor nerve conduction Electrical stimulation of a motor nerve normally produces contraction of the muscles supplied by that nerve.The time interval between stimulation of the nerve and the appearance of the motor action potention MAP is the latency Normal values are about 50-60 msSomatosensory evoked potentials SEPs - This test is useful in monitoring the integrity of the spinal cord during operative correction of severe spinal deformities and other potentially dangerous procedures
