Answer:
Does the brain send it messages? Muscles move on commands from the brain. Single nerve cells in the spinal cord, called motor neurons, are the only way the brain connects to muscles. ... When the impulse travels down the axon to the muscle, a chemical is released at its ending.
Explanation:
Neurons communicate with each other by sending chemical and electrical signals. ... Each neuron is connected with other neurons across tiny junctions called “synapses”. Impulses rush along tiny fibres, like electrical wires, from one neuron to the next.
