Question

Quizplus · Accepted Answer

Hormones are indeed chemical messengers like neurotransmitters, but unlike neurotransmitters, which are typically released by neurons and act on nearby cells, hormones are released into the bloodstream and can affect cells at distant sites in the body. This systemic distribution is a key difference. Hormones are regulated by the brain and other factors, and they are not by-products of neurotransmitters; they are distinct entities with different roles in the body.
