Question

Which of the following terms describes how a neuronal membrane's potential is altered in the presence of inhibitory signals? View Available Hint(s) Which of the following terms describes how a neuronal membrane's potential is altered in the presence of inhibitory signals? Depolarization. Polarization. Hyperpolarization. Repolarization.

Answer 1

Hyperpolarization

Step-by-step explanation:

When the membrane potential becomes more negative than the resting potential, the membrane is hyperpolarized. Hyperpolarization is inhibitory in nature and decreases the ability of the neuron to generate a neural impulse. During signal transmission at a chemical synapse, binding of neurotransmitters to the receptors stimulates the opening of ligand-gated ion channels. The flow of ions changes the voltage across the membrane and may cause depolarization or hyperpolarization. For instance, the opening of Cl– or K+ channels causes hyperpolarization.
