| The alimentary canal is not innervated via the ventral nervous system as has been claimed earlier. |
| Individual muscle fibers may be innervated by one or both of the excitatory neurons, and generally receive inhibitory input as well. |
| The striated muscles innervated by cranial nerves are usually affected the most severely. |
| Both the foot and the parapodia are innervated by nerve trunks originating most often from the pedal ganglia. |
| The smooth muscle portion of the esophagus is innervated by neurons within the dorsal motor nucleus of the vagus. |
| It is innervated by the anterior interosseous nerve and may be represented as the tibialis posterior of the leg. |
