Different motor units generate the same potentials in an EMG readout. True or False

Different motor units generate the same potentials in an EMG readout.

True or False

Expert Solution

Ans:- FALSE

Concept :- see different motor units have different no of muscles fibers . And as the no of muscle fibers which are recruited to do the work increase there is incresing degree of superimposition of action potentials from different units. With increasing force, the EMG becomes continuously denser and the maximal peaks in the signal have a higher amplitude.

U can understand the motor unit summation from below
