The Vital Role of Resting Membrane Potential in Neural and Muscle Function: Explained

Define ‘resting membrane potential.’

Membrane potential at which membrane is at rest. (no action potential)

Resting membrane potential refers to the electrical potential difference that exists across the cell membrane of a neuron or muscle cell, when it is at rest and not transmitting any electrical signal. At rest, the inside of the cell is more negative than the outside, and this difference in electrical charge is maintained by the selective permeability of the cell membrane to different ions, including sodium (Na+), potassium (K+), chloride (Cl-), and other ions. The resting membrane potential is typically around -70 millivolts (mV) in neurons and muscle cells, and it plays a critical role in the initiation and propagation of electrical impulses that are essential for neural and muscle function.
