Summary Introduction

To name: The neurotransmitter that is acting at “postsynaptic synapses of the parasympathetic and sympathetic systems”.

Introduction: The neurotransmitters are endogenous chemicals released by the neurons and are localized in the presynaptic terminal (terminal end of the axon). These chemical signals are released into the synaptic cleft and bind to specific receptors on the postsynaptic membrane of another neuron. The neurons that are present in a specific portion of the brain can be directly or indirectly influenced by each neurotransmitter, thereby affecting the behavior. The transfer of the impulses across the synapse depends on these neurotransmitters.
