Quizplus · Accepted Answer

Hormones are chemical substances produced by glands that regulate the activity of cells or organs, affecting body functions and behavior. Neurotransmitters are chemicals that transmit signals across a synapse from one neuron to another. Neurilemma is the outermost layer of a nerve fiber. Enkephalins are types of endorphins involved in regulating pain and reward, but they are not secreted by glands to affect body functions in the broad sense that hormones do.
