The nerves may consist of sensory, motor or both types of fibers, and depending on this the nerves may be sensory, motor or mixed correspondingly. Likewise, there are connectives running between ganglia of the same side, and commissures among the ganglia of the opposite side. They mostly consist of association fibers.
