At an excitatory synapse, an action potential in the presynaptic neuron increases the A) membrane potential of the postsynaptic cell membrane B) permeability of the postsynaptic cell to both Na⁺ C) permeability of the postsynaptic cell to Cl^- D) all of these E) membrane potential of the postsynaptic cell membrane and permeability of the postsynaptic cell to both Na⁺

Question

Quizplus · Accepted Answer

At an excitatory synapse, the action potential increases the permeability of the postsynaptic cell to Na+, leading to depolarization and increased likelihood of an action potential.

At an Excitatory Synapse, an Action Potential in the Presynaptic
