PRE-LAB LECTURE #2 RESTING MEMBRANE POTENTIAL
Objectives o Measure resting membrane potential (Vm) in frog muscle using glass microelectrodes o Examine how Vm depends on extracellular [K+]o. o Evaluate relationship between Vm and [K+] o All living cells under resting conditions have an electrical potential difference o Inside = negative o Outside = zero (by convention)
