How Neurons Work (1 of 3): Neuron Structure and Resting Potential (BioFlix tutorial)?
fiasKO [112]

 A neuron is nerve cells that transfer information within the body, chemically over short distances, using electrical signals over long ones.

   As it turns out, most resting neurons are permeable to Na+ and CL- as well as K+. K+ will try to drag the membrane potential toward its (positive) equilibrium potential, while NA+ try to drag the membrane potential to its negative equilibrium potential.

The real membrane potential will be between NA+ and K+ of equilibrium potential<span>. However, it will be closer to the equilibrium potential of the ion type with higher permeability.</span>
