The brain controls the body through a constant series of electrical impulses. If the body is full of fluids and tissue then what stops the body from constantly short circuiting?

The brain controls the body through a constant series of electrical impulses. If the body is full of fluids and tissue then what stops the body from constantly short circuiting?

Answer 1

The nerves are wrapped in a substance called myelin, which insulates them (not letting the electricity go somewhere else). Each neuronal impulse can reach -80 mV, so it’s not that much energy to cause “short circuit”.

Although, there are part of the nervous system that are demyelinated, but, you know, lipids (fat) are good insulators, and most of the cell membranes are made of lipids.
