Neurophysiology Resting Potentials

Voltage is a measure

• Electrical resistance

• Electrical current

• Electrical potential

• Electrical concentration

The resting membrane potential is typically

• -55mV, the inside is more negatively charged than the outside

• -55mV, the inside is more positively charged than the outside

• -70mV,the inside is more negatively charged than the outside

• -70mV,the inside is more positively charged than the outside

Which two ions are mainly involved in generating a resting potential.

• Sodium and potassium

• Sodium and calcium

• Potassium and calcium

• Calcium and chloride

The sodium/potassium pump

• removes 2 sodium ions for every 3 potassium ions brought into the cell

• removes 3 sodium ions for every 2 potassium ions brought into the cell

• removes 2 potassium ions for every 3 sodium ions brought into the cell

• removes 3 potassium ions for every 2 sodium ions brought into the cell
