WebJun 14, 2024 · The stimulus triggers the sensory neuron to send a signal then carries information towards the central nervous system. Specifically, depolarization is initiated at the sensory receptors and transmitted along the dendrites to the cell body and then to the axon. At the axon terminal, the signal initiates the release of chemicals into the synapse. nancy byers farrelly
