Quizplus · Accepted Answer

Neurotransmitters are the chemical messengers for the nervous system, which are released into the synaptic cleft to transmit signals from one neuron to another. Hormones are chemical messengers for the endocrine system, which are released into the bloodstream to regulate various body functions. While some hormones can affect the nervous system, they are not the primary chemical messengers for it.
