Well, post ganglionic neurons are simply those neurons that synapses that connect to our pre ganglionic neuron. So the pre ganglionic neuron begins at the central nervous system. It extends into the peripheral nervous system and then it connects with the post ganglionic neuron. And the post ganglionic neuron then carries that electric signal to some type of target organ or target cell known as our effector or effector organ. So the post ganglionic neurons are the cells that synapse or connect with the pre ganglionic neurons coming from the central nervous system. And this takes place within the autonomic division of the peripheral nervous system.
