Chapter 48, Problem 16TYK
Summary Introduction
Introduction: Neurotransmitters are released during the nerve impulse conduction. They are chemical molecules that are released by the neurons in response to a stimulus, which excites the other neurons and brings about a nerve signal impulse transmission. The most abundant neurotransmitters are acetylcholine (ACh), dopamine, GABA, and so on.
