KZ, question: I understand the physiology of the Lazarus sign as far as the nerve pathway, but don't understand how it originates. Is it just random nerve movement because the body is still functioning even if the brain isn't? If so, why does Israel respond that way every time his mom touches him? Also, are the arms the only place that nerve transmission is seen or are there other areas of the body that can move?
Thanks in advance!
I have to run, but will answer more later. There are a number of stimuli that can cause muscular movement. I'm not trying to be funny, but here is a video that might explain this more graphically. It's fresh frog legs, moving in response to the stimuli (salt-- an electrolyte). There is no question that the 3 unfortunate frogs who previously owned these legs are dead. Of course, a human mammal is not an amphibian, but these frog muscles are responding to the stimuli just like mammal muscles might.
In fact, there is a diagnostic test for a very serious condition called Malignant Hyperthermia, a genetic disease where patients have life threatening reactions to some anesthesia drugs. In that test, a muscle contracture test, a fresh sample of thigh muscle is removed surgically, and exposed to triggers to see if the patient has MH.

Here's the frog legs with the sodium chloride stimulant:
