Henneman's principle

from Wikipedia, the free encyclopedia

The Henneman principle (after Elwood Henneman ) describes the process in the body during which information from the neuron in the brain reaches the respective fiber ends.

The small motor units of the slow-twitch type are recruited when there is little effort required, the large, strong motor units of the fast-twitch type when the effort is highest.

Henneman described the experimental basis of the size principle in 18 logically related publications in the Journal of Neurophysiology over a period of 25 years.
