Explanation:
Detailed explanation-1: -Neurotransmitters are the chemicals that transmit the nerve impulse across the synapse. They are stored in synaptic vesicles of axon terminal and are released into the synaptic cleft. Acetylcholine is the neurotransmitter secreted by both pre-and post-ganglionic parasympathetic cholinergic neurons.
Detailed explanation-2: -A neuron sending a signal (i.e., a presynaptic neuron) releases a chemical called a neurotransmitter, which binds to a receptor on the surface of the receiving (i.e., postsynaptic) neuron. Neurotransmitters are released from presynaptic terminals, which may branch to communicate with several postsynaptic neurons.
