Resting Potential
Definition
Resting potential refers to the state of a neuron when it's not being stimulated or sending signals. It's the difference in electric charge between the inside and outside of a neuron's cell membrane.
Analogy
Resting potential is like a car parked on top of a hill. It's not moving, but it has the potential to do so because of its position. Similarly, a neuron at resting potential isn't sending signals, but it has the potential to do so due to its electrical charge.
Related terms
Action Potential: This is an electrical impulse that travels down the axon triggering the release of neurotransmitters. It occurs when a neuron sends information down an axon, away from the cell body.
Threshold: The level of stimulation required to trigger an action potential in neurons.
Hyperpolarization: An increase in the membrane potential of a cell relative to its normal resting potential, making it less likely for an action potential to occur.
