D)diffusion,electrical gradient

Question

Quizplus · Accepted Answer

Excitatory and inhibitory refer to the effects that neurotransmitters can have on postsynaptic neurons. Excitatory neurotransmitters cause depolarization, making the neuron more likely to fire an action potential, whereas inhibitory neurotransmitters cause hyperpolarization, making the neuron less likely to fire an action potential. The terms hypopolarizing and hyperpolarizing specifically refer to the effect of a current on the resting membrane potential of a neuron. Hypopolarizing currents will make the neuron more likely to fire an action potential (similar to excitatory neurotransmitters), whereas hyperpolarizing currents will make the neuron less likely to fire an action potential (similar to inhibitory neurotransmitters). Therefore, the correct answer is B.
