Nervous System
- the nerve center of tapeworms is located in the scolex
- the complexity is depended on the complexity of the scolex - bothriate cestodes are the simplest, with only a lateral pair of cerebral ganglia united by a single ring and a transverse commissure
- worms with bothridia or acetabula are much more complex and hence have a more complex system of commissures and connectives in the scolex, with five pairs of longitudinal nerves running posteriorly from the cerebral ganglia through the stroblia
