Neurotransmitters that open Na⁺ channels and trigger action potentials in receiving cells are called

Question

Quizplus · Accepted Answer

Neurotransmitters that open Na⁺ channels and trigger action potentials in receiving cells are called excitatory. Inhibitory neurotransmitters have the opposite effect, causing hyperpolarization and decreased likelihood of an action potential being generated. Cross-linked and obligatory are not commonly used terms in describing neurotransmitters.
