Chapter 33.8, Problem 1LO
Summary Introduction
To explain: The musculature of a nematode that allows it to wriggle in a highly characteristic manner.
Introduction: Bilaterians are animals with bilateral symmetry, which means the left and right sides of the embryo are mirror images. The bilateral symmetry allowed these animals to achieve high levels of specialization within parts of their bodies, such as the concentration of sensory structures at the anterior phores is truly bilateral.

Explain the interaction of cuticle, body-wall muscles, and pseudocoe-lomic fluid in locomotion of nematodes.
do any nematodes have similar adaptations due to their needs being met by their hosts? I know that nematodes are parasitic and not mutually beneficial, but they are still symbionts and perhaps have evolved to no longer require some components of basic anatomy in result of their needs being met by their host. please cite sources
