Define resting membrane potential and mention its significance.

Webthe resting membrane potential for a neuron is -70mv while that of a red blood cell is only -10mv.This brings up an important concept: some cells are excitable, meaning they can be stimulated to experience a very predictable and rapid change in membrane potential. These are called action potentials and will be discussed later. Web4/10/23 11 Membrane potential is governed by ion distribution and permeability to specific ions 1. Electricity in water is carried by ions (+ or -) 2. Ion flow is detected as electric current 3. Accumulation of ions, if not balanced, is detected as accumulation of charge or membrane potential 4.
