Quizplus · Accepted Answer

A neurohormone is a chemical messenger that is produced by neurons and released into the bloodstream, where it can act on cells in distant parts of the body. In this case, the neurohormone is released from the hypothalamus and acts on cells in the pituitary gland to regulate the secretion of hormones. Neuromodulators and neurotransmitters are also chemical messengers produced by neurons, but they act locally within the nervous system rather than being released into the bloodstream. Neuroenzymes are enzymes that are produced by neurons and involved in chemical reactions within the nervous system.
