#9 Kinetic Catastrophes3          We're all mechanical animals of sorts, our locomotion made possible by the links between muscles, tendons, skeletal elements and much more. The human central nervous system controls all of our muscular activity by firing electrical signals from the brain to muscle cells, which twitch in response to the gray matter's commands. When part of that system goes awry, we don't move much, if at all.4          And yet, there is so much confounding zombie behavior. They stagger around — sometimes with frightening speed — even when their flesh and bones are dangling and flopping. Many zombies also appear to suffer from massive head wounds that would result in brain damage, making the idea of forward motion all the more implausible.*1 pointZombies mostly stumble around but sometimes move with frightening speed.Zombies do not have a functioning central nervous system, so in reality in would be impossible for them to move around.Humans have a central nervous system that control our movement.Many zombies have brain damage that wouldn't allow them to move.
