Neurotransmitters are the body's chemical transmitters. Their task is to send nerve cell messages to target cells. The target cells might be found in muscles, glands and other nerves. In order to control many of the processes needed for the brain, it needs neurotransmitters including: heart rate, respiration, circadian rhythms, digestion. The nervous system regulates the organs, psychological and physical operations of the individual. The neurotransmitters of nerve cells, also known as neurons, have a substantial function. The cells of the nerves fire impulses. This is done by the release of neurotransmitters, chemical substances that relay signals to other cells. Each neurotransmitter binds to another receptor — for instance, dopamine molecules attach to the receptors of dopamine. This initiates action in the target cells when they are coupled. The body eliminates or recycles them after neurotransmitters send their messages.
