Alary muscles are a pair of triangular fans like muscles in the heart or pericardial sinus of the cockroach. The respiratory movements of abdomen and contraction of alary muscles increase the pumping force of the cockroach's heart. It lies immediately on top of the dorsal diaphragm. In the abdomen of the insect, the dorsal vessel is called as a heart. It is divided segmentally into chambers that are separated by valves (Ostia) to ensure one-way flow of hemolymph. A pair of alary muscles is attached laterally to the walls of each chamber and circulates hemolymph chamber to chamber.
