State
The autonomic nervous system controls internal organs without conscious control, relaying signals through two synapses: a preganglionic neuron synapsing onto a postganglionic neuron reaching the target organ.
Show
A preganglionic neuron often synapses onto multiple postganglionic neurons, amplifying one signal across many cells.
Watch for
The sensory-somatic system uses only one synapse between the central nervous system and its target — this relay is distinctive.
