Abstract

Transection experiments of hearts in male and female house flies, Musca domestica L., indicate that there are at least 11 regions in the female and 10 in the male that can beat for extended periods. The beat does not appear to be contingent upon the alary muscles, heart continuity, size of heart segments, or heart symmetry, and evidences no constant starting point in the intact heart.
