Wondering about a missing truism

I have found that several truisms resemble well known scientific laws. But I know one form of scientific law that, so far, has not been "resembled" by a known truism. Anyway this form says: "the toe bone is connected to the foot bone, the foot bone is connected to the leg bone, the leg bone is connected to the knee bone, ......". We know this 'law' also as it appears in the definition of narrative continuity. It is certainly a rule of polyphony. So is this a missing truism of some sort?
