Henneman's size principle refers to the
WebSINCE THE BEGINNINGS OF NEUROHISTOLOGY it has been recognized that neurons within the central nervous system vary widely in size, but the functional significance of this basic observation has never emerged from the realm of speculation. The largest cells have surface areas which are at least 100, perhaps 1,000, times greater than those of the … WebDescripción. La Ley de Henneman (también denominada "principio del tamaño") establece que, dado que el tamaño de las motoneuronas determina su umbral de excitación, durante la aplicación de una fuerza muscular las unidades motoras de menor tamaño serán las primeras en reclutarse, y en la medida en que el esfuerzo lo requiera, se irán ...

WebThis so-called size principle permits a high precision in muscle force generation since small muscle forces are produced exclusively by small motor units. Larger motor units are activated only if the total muscle force has already reached certain critical levels. We show that this recruitment by size is not only optimal in precision but also ...
