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.
