Question

Quizplus · Accepted Answer

Neurons communicate with each other by releasing neurotransmitters, which are chemical messengers that are released from the axon of one neuron and bind to receptors on another neuron. This binding initiates a response within the second neuron, which may lead to the generation of an action potential and subsequent transmission of the signal. Precursors are substances that are converted into neurotransmitters within neurons, and hormones are chemical messengers that are released by endocrine glands and travel through the bloodstream to act on target tissues. Peptides are a type of neurotransmitter, but not all neurotransmitters are peptides.
