Membrane Potential

What is Membrane potentials?

• electrical currents in the blood
• electrical energy across a cell membrane
• potential blood in the ventricular systole

Which part of the cell acts as the conducting materal?

• cytoplasm
• positive ions
• negative ions

What happens to the cell during hyper-polarization?

• membrane is less negative inside, more positive outside
• membrane is more positive inside, negative outside
• membrane becomes more neg inside and more positive outside

What happens during hypopolarization or Depolarization?

• membrane becomes less neg inside the and less pos outside
• membrane is more neg inside, more pos outside
• membrane is less neg inside, more pos outside

What causes the membrane potentials to change?

• Potassium Ions
• The Ions itself
• The Ions and there movements across the Plasma membrane
• Sodium Ions and there movements

Which ion is permeable to the pm at rest?
