Distinguish between the actions of excitatory and inhibitory neurotransmitters.
The neurons are specialized cells of the human nervous system. The neurons communicate with each other as well as other cells by transmission of nerve signals through action potential. The action potential refers to the rapid changes in the membrane potential of neurons. The point of contact at which communication occurs between two neurons is called synapse. The synapse structure involves two types of neurons: presynaptic neuron which sends the nerve signals, and postsynaptic neuron which receives the nerve signals.
In a chemical synapse, the electrical signals from the neurons are converted into the release of the chemical neurotransmitters which are transported across the small distance between the presynaptic neuron and postsynaptic cell. Different types of neurotransmitters include glutamic acid, GABA (gamma- Aminobutyric Acid), acetylcholine, norepinephrine, and others.
