Anatomy
| Neurotransmitter | Actions |
|---|---|
| acetylcholine (located in neuromuscular junctions, autonomic nervous system, and brain) | excites muscles, decreases heart rate, and relays various signals in the autonomic nervous system and the brain |
| norepinephrine (located in sympathetic nervous system and brain) | regulates activity of visceral organs and some brain functions |
| dopamine(located in brain) | involved in control of certain motor functions |
| serotonin (located in brain and spinal cord) | maybe involved in mental functions, circadian rhythms, and sleep and wakefulness |
| gamma-aminobutyric acid (located in brain and spinal cord) | inhibits various neurons |
| glycine (located in spinal cord) | inhibits various neurons |
