Summary Introduction
To review:
The excitatory and inhibitory neurotransmitters and the mechanism of their action.
Introduction:
Neurotransmitters are the chemicals that help in neurotransmission across the chain of neurons. They are released from the axon of one neuron end to the target neuron through neuromuscular junction or chemical synapse to transmit the chemical signals.
