Summary Introduction

To explain: List the sequence of events that take place in synaptic transmission and draw diagram to support this answer.

Introduction: Signal transduction is possible because of specialized nerve cells called neurons. Neurons are made up of receiver units which receive signals called dendrites and sender units which send the information outside the neurons. The signal travels as a wave of depolarization along the membrane of neuron. In case of myelinated neurons it jumps to the nodes by saltatory conduction. But neurons are not physically joined together, so signal is transmitted at the neuron junction known as synapse.
