| Description: 1 Dendrites and the cell body are an input zone. They receive chemical signals from another neuron and convert them to electrical stimulation. 2 The stimulation spreads to a trigger zone at the start of an axon. 3 If the electrical signals are sufficiently strong, they are conducted along the axon to its terminal endings. 4 Axon terminals are a signal output zone. They release chemical signals that influence another cell. In the case of a motor neuron the signals affect a muscle cell.
