The setae are small spines which are projected from the body wall by muscles to act as anchors in the surface that the worm is moving along. The muscle can also retract the setae
The circular muscles contract and expand in co-ordination with the longitudinal muscle in series such as that if the posterior muscle are expanded and the anterior circular muscles are contracted the worm pushes and stretches its front end forward. The anterior muscles then expand to anchor its front end by use of the setae and the rear end is pulled forward. All this happens in a smooth and rhythmic motion.
