Quizplus · Accepted Answer

Hormones are slow-acting chemical messengers that travel through the bloodstream to target cells in various organs and tissues. They have long-lasting effects and can influence growth, development, metabolism, and other physiological processes. Neurotransmitters, on the other hand, are chemical messengers that are released from neurons to transmit signals across synapses to other neurons or target cells. Acetylcholine and dopamine are specific neurotransmitters that play important roles in various brain functions and behaviors.
