Synaptic transmission is the process by which one neuron communicates with another, The information is passed down the axon of the neuron as an electrical impulse known as an action potential, When the action potential reaches the end of the axon it needs to be transferred to another neuron or tissue, The synapse permits a neuron (or nerve cell) to pass an electrical or chemical signal to another neuron or to the target effector cell in the nervous system, Synapses are important to the transmission of nervous impulses from one neuron to another.
