Sep 21, 2006 · • Size principle: Smaller hypotheses receive greater likelihood, and exponentially more so as n increases. Therefore, individual MUPs studied at low effort during EMG belong to small type 1 motor units . When the central nervous system sends stimulatory input to a particular muscle, the motor units innervating that muscle are recruited in an orderly manner, following the size principle: The first motor units to be activated are those with the smallest axons.

Now, here’s where the size principle ties together with the muscles. In addition to the eddy-current loss, the change in particle size also has great influences on the effective demagnetizing field within SMC and thus affects the permeability, the DC-bias performance and the hysteresis loss [20]., 1965a); the alternative is that different premotor neurons provide input to different subsets of motor neurons.
