The neuron “communicates” from the stimulus to muscle action through the synapses connecting each neuron. These neurons use neurotransmitters to send chemical and electrical signals through the neuron. The dendrites assist in this process of communication by accepting the neurotransmitters that move down the synaptic gap/stimulus. If the dendrite accepts enough neurotransmitters on its receptors, it sends an electrical impulse through it to the information stored in the cell body. Overall, the millions upon millions of neurons form millions upon millions of connections forming a complex system which sends signals rapidly.
