|
Relationship between motor unit size and force |
The larger the motor unit the greater the force. Ex- quads vs soleus |
|
|
Relationship between axon diameter and force |
The greater the diameter of the axon, the greater forced produced because of the greater action potential (think of a large hose for water vs a small hose) |
