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.
