Hormones: they are the chemicals of the endocrine system used to send messages to organs and tissue throughout the body
neurotransmitters: a chemical substance released at the end of a nerve fiber at the arrival of a nerve impulse, by diffusing across the synapse, which then causes the transfer of the impulse to another nerve fiber, etc.
Hormones and neurotransmitters are equally both similar and different in many ways. A characteristic that they both share, is that they are both forms of sending messages into the body. The only difference being, a neurotransmitter is sends signals to balance target cells, aka muscles or glands. Hormones send messages and signals throughout the body and organs.
