There are three kinds of chemical messengers in the nervous system: Neurotransmitters, endorphins and hormones.

1) Neurotransmitters are released by transmitting neurons. They alter the activity of the receiving neurons. Note that neurotransmitters exist outside of the nervous system as well. Some neurotransmitters are: Serotonin, dopamine, acetylcholine, gamma-aminobutyric acid (GABA), norepinephrine (also a hormone) and glutamate.

2) Endorphins help in pain reduction, pleasure and even memory.

2) Hormones are affects the functioning of organs and are released by glands. Some hormones include: Melatonin, oxytocin, adrenal hormones (cortisol, epinephrine, norepinephrine) and sex hormones (androgens, estrogens and progesterone).
