A few Neurons questions

• In a myelinated axon, what best explains why action potentials appear to "jump" from one node of Ranvier to the next during saltatory conduction?
• In a typical neuron at rest, which ion’s concentration gradient is the main reason the membrane potential sits near the potassium equilibrium potential rather than the sodium equilibrium potential?
• In a spinal reflex circuit, what is the main role of a sensory-motor interneuron?
• Which statement best describes the main functional role of dendritic spines on many neurons?

How it works

Pick a topic — any topic you can type — and TrivAI writes the questions, checks them against sources before serving, and fixes them when players report a problem. Answer before the fuse burns out to score double. Every 10 questions you can cash out or keep going, then challenge a friend to the exact same set.
