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).
These chemical messengers of brain are serotonin, dopamin and noradrenalin.
These chemicals are called hormones.

a hormone
well i kno they discovered hormones in 1902 but a hormone in itself is a chemical messenger so therefore it was the hormone
ENDORPHINS which are produced by the central nervous system and pituitary gland. The part of this word -ORPHIN is short for the chemical MORPHINE. A side effect is it may produce on you a euphoric feeling.
If you can consider alcohol a drug, it is a nervous system depressant.

the nervous system serves as a messenger service to the brain
nervous nd hormonal systems
Nervous system is built for speed, it uses impulses to prod the muscles and glands into immediate action. Whereas, the endocrine uses a chemical messenger called hormones, which is release into the blood to be transported leisurely through out the body.

Silica is the chemical that can damage the central nervous system cardiovascular system reproductive system hematological system and kidney with exposure.
Chemical
Nervous System - since brain and the spinal cord are part of it.
Chemical coordination takes place in animals with the help of hormones.Hormone is the chemical messenger that regulates the physiological processes in living organisms. It is secreted by glands. The regulation of physiological processes, and control and coordination by hormones comes under the endocrine system. The nervous system along with the endocrine system in our body controls and coordinates the physiological processes.

There isn't any. You're thinking of the nervous system - but the messages are all chemical. The electrical activity is a side effect.
