locations and the neuron also has an output wire called the axon.

and then it sends outputs, via its axon to other nodes or other neurons in the brain.

Our brain is made up of billions of active neurons, around 170,000 km of combined axon length.

So, here's one neuron and what it does is if it wants to send a message, what it does is it sends the little pulse of electricity via its axon to some difference neuron and here this axon.

The soma is the cell body, the axon is the sending end of the neuron, the dendrite is the receiving end of the neuron.

And if we make it fire hard enough, we can get through the axon, we can activate the next neuron, the neuron on the right.

Sorry to use philosophical terminology here, but when it's secreted at the axon end plates of the motor neurons, a whole lot of wonderful things happen in the ion channels and the damned arm goes up.

Those little blue dots on the top are the transmitters released by the axon, and then they activate all of these receptors, and all of that machinery in the next neuron, and ultimately that causes the neuron to fire.

Connects to the input wire or connects to the dendrite of this second neuron over here, which then accepts this incoming message does some computation and may in turn decide to send out its O messages on its axon to other neurons.

So a typical cell, like the neurons in our brain, has a region called the dendrites that receives input, and that input sums together and will produce action potentials that run down the axon and then activate all the output regions of the neuron.

I mean, we don't know the detailed answer, but we know the basic part of the answer, and that is, there is a sequence of neuron firings, and they terminate where the acetylcholine is secreted at the axon end plates of the motor neurons.
