What are six different neurotransmitters and where do they occur in the body?

First, acetycholine, an excitatory neurotransmitter, is found in the preganglionic and postganglionic parasympathetic nerves, the preganglionic sympathetic nerve, and the nerve to the sweat gland. Second, dopamine, an inhibitory neurotransmitter, is found in the limbic system and basal ganglia. Third, GABA, an inhibitory neurotransmitter, is found in the cerebellum, retina, and spinal cord. Fourth, serotonin is found in the hypothalamus, the GIT, the lung, and platelets. Fifth, noradrenaline, an excitatory neurotransmitter, is found in the postganglionic symathetic nerve and the brain stem loncus ceruleus in the pons.

1. Acetylcholine - Found in the neuromuscular junctions and throughout the central nervous system.
2. Dopamine - Present in various regions of the brain, including the substantia nigra and the ventral tegmental area.
3. Serotonin - Located primarily in the brainstem and gastrointestinal tract.
4. Glutamate - Predominantly found in the central nervous system, serving as the primary excitatory neurotransmitter.
5. Gamma-aminobutyric acid (GABA) - Abundant in the central nervous system, acting as the primary inhibitory neurotransmitter.
6. Norepinephrine - Found in the brainstem, particularly in the locus coeruleus, and in sympathetic nerve endings throughout the body.
