PATHOLOGY

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: -Neurotransmitters pass through the synapse, the gap between two nerve cells, and attach to receptors on the receiving cell. This process repeats from neuron to neuron, as the impulse travels to its destination-a web of communication that allows you to move, think, feel and communicate.
