Resting membrane potential is the electrical potential difference across the plasma membrane of a neuron or muscle cell when it is not actively transmitting a signal. This potential typically ranges from -70 to -90 mV, largely maintained by the distribution of ions, especially sodium (Na+), potassium (K+), and chloride (Cl-) across the membrane. Understanding resting membrane potential is crucial as it establishes the conditions necessary for action potentials, which are fundamental to bioelectric signaling.
congrats on reading the definition of Resting Membrane Potential. now let's actually learn it.
