We have a fixed number of neurons, which means they do not regenerate. Neuron is a specialized nerve cell that receives, processes, and transmits information to other cells in the body.

ACh is the neurotransmitter within these ganglia, and the ACh binds to nicotinic receptors on postganglionic neurons (see the following figure). From these neurons arise relatively long postganglionic fibers that travel to their target organ and release norepinephrine as the primary neurotransmitter.
