how do humans emit electrical impulses?

Answer 1

They don't. Electrical impulses travel through the body in our nervous system as a result of the opening and closing of gated ion channels. The body emits thermal radiation (heat.)

Answer 2

Other than static charges accumulated in your body, that can amount to very large voltages and perceptible currents (but very rarely dangerous ones) there is almost no other electrical impulses the body emits.

Yet, if you meant electromagnetic signals leaving your body, and if we pay attention to very faint signals, we should take into account micro voltages in the skin like the ones used for an electrocardiogram (ECG) or an Electroencephalography, these are such small potentials that putting a spoon in detergent with a copper wire would yield a voltage thousands of times bigger.

There is also a continual emition of very weak electromagnetic signals from the electrical currents in our nervous system, nothing as big as to appear on a photograph, but big enough to be detected by very sensible apparatus, an example if this is Electroencephalography but even this requires thousands of neurons to be detected.

In orders of magnitude, the signals emitted by the body in relation of TV or Cell Phone transmitions wold pale like the light of a candle in front of the light of the sun (to light a large area).

Answer 3

Nerves transmit commands using electrical impulses. These impulses make musles move and the brain work. The electricity itself is made from chemical reactions in the nervous system.

Answer 4

Yes you can get charged up electrostatically and give a shock to some accidentally.
The human body emits radiation and each one is different.
Based on this fact your radiation foot prints can be idendtified via satelite.

Answer 5

Look at the last two people, they explained it well. However, these are never emitted and fairly faint...

Answer 6
