Anal cerci are multisegmented, jointed filamentous structures in the 10th abdominal segment that are sensitive to sound and vibrations. These structures are found in both sexes. In cockroaches, Malpighian tubules around 100–150 are present in number and are excretory in function. Spiracles are the organs that play an important role in respiration. A pair of anal styles are only present in the male cockroaches and are the male copulatory structure which helps in mating.
