Vedclass · Answer

(C) In $Pheretima$ (earthworm),locomotion is achieved through the coordinated action of the body wall muscles and the setae.$1$. The body wall contains both circular and longitudinal muscles.$2$. Contraction and relaxation of these muscles cause changes in the body shape,allowing the earthworm to move.$3$. Setae,which are $S$-shaped chitinous structures embedded in the epidermal pits of each segment (except the first,last,and clitellum),act as anchors to provide grip against the substrate during movement.$4$. Therefore,the combined action of longitudinal muscles,circular muscles,and setae facilitates locomotion.
