How does the number of the motor units relate to the function of the muscle?
- Bottom Line: Motor units cannot vary the amount of force they generate; they either contract maximally or not at all.
- Examples:
1. If the stimulus is strong enough to trigger an action potential, then it will spread through the whole length of the muscle fiber. It will spread through all muscle fibers supplied by a single nerve.
2. If the stimulus is not strong enough, then there will be no action potential and no muscle contraction.
-Muscles that have to control precise movements are made up of many small motor units. (eyes have 10-20 fibers to a unit) (gastrocnemius has 2000-3000).
