Question

If both motor neurons shown in this figure were to develop action potentials and stimulate muscle fibers, would all the muscle cells shown here contract?

Answer 1

Below are the choices that can be found elsewhere.

-No, because neurons in this figure do not innervate every muscle cell shown. 
- Yes, because signals can be passed from stimulated muscle fibers to unstimulated ones. 
- Yes, because an entire muscle only needs one neuron to stimulate it in order to contract. 
- No, because it is impossible for more than one motor unit to contract at once

The answer is -No, because neurons in this figure do not innervate every muscle cell shown.
