How Do Nonspiking Neurons Function Even Though Their Depolarization Signal

question 13

Multiple Choice

How do nonspiking neurons function even though their depolarization signal significantly degrades with distance?

• A) Voltage-gated Na⁺ channels are replaced by ligand-gated Na⁺ channels.
• B) These neurons are very short, so there is no major signal decrement.
• C) There are sufficient numbers of voltage-gated Na⁺ channels to convey the signal without major decrement.
• D) Voltage-gated K⁺ channels compensate for the lack of voltage-gated Na⁺ channels.
