Vedclass · Answer

(D) Locomotion in the earthworm $(Pheretima)$ is achieved through the coordinated action of the body wall muscles (circular and longitudinal muscles) and the $Setae$. $1$. The $Setae$ are $S$-shaped structures embedded in the epidermal pits of each segment (except the first,last,and clitellum),which provide grip on the soil. $2$. The circular muscles cause the body to elongate,while the longitudinal muscles cause the body to shorten. $3$. By alternating these contractions and using the $Setae$ as anchors,the earthworm moves forward.
