Following repolarization, the neuron may become slightly hyperpolarized before it re-establishes its resting membrane potential.
RoseWind [281]
<h2>Membrane potential </h2>

Explanation:

  • Membrane potential represents charge difference across the membrane, all biological cells are negative inside (cytoplasm) and positive outside (due to difference in ionic distribution)  
  • In a typical neuron cell membrane potential of cytoplasm is negative at rest (when no stimulus is applied) hence called resting membrane potential
  • Resting membrane potential of excitable cells is established by Na+ and K+pump
  • Repolarization starts with the efflux of K+ by the opening of voltage gated K+ channels
  • Voltage gated K+ channels starts to open when voltage gated Na+ channels becomes inactive
  • Hyperpolarization occurs due to excessive efflux of K+ by voltage gated K+ channels
  • Additional efflux of K+ occurs due to slow inactivation of voltage gated K+ channels
