Questions & Step-by-Step Solutions

What is the resting membrane potential of a typical neuron? (2020)
  • Step 1: Understand that a neuron is a type of cell in the nervous system.
  • Step 2: Know that neurons have a difference in electrical charge across their membrane.
  • Step 3: This difference in charge is called the resting membrane potential.
  • Step 4: The resting membrane potential is measured in millivolts (mV).
  • Step 5: For a typical neuron, this resting membrane potential is around -70 mV.
  • Step 6: The negative sign indicates that the inside of the neuron is more negatively charged compared to the outside.
