Explain what factors, structures, and ion channels contribute to establishing and maintaining the resting membrane potential. Draw a cell and show all relevant contributors to the resting membrane potential with explanations of how they contribute to establish and maintain the resting membrane potential.

What cells have a resting membrane potential? Is it only nerve and muscle (excitable) cells?

Name the 4 ion channels that contribute to the maintenance of the Resting Potential. Include (i) whether the ion channels use active or passive transport, (ii) which ion moves only by passive transport, (iii) the 3 ions involved in selective permeability, and (iv) the single ion most responsible for maintaining -70 mv across the membrane.

Dr.W is trying to explain the concepts of resting membrane potential, equilibrium potential, and membrane potential to the students in her laboratory. To do this, she uses a dish of cultured motor neurons so that she can alter the solution covering the cells and she can use a recording electrode to pierce one of the cells and determine its membrane potential relative to the extracellular fluid. She asks you a number of questions before and after she alters the conditions...
