1
New cards
Cell membrane separate charges
ICF (-) relative to ECF (+)
membrane is polarized
RMP occurs only across cell membrane (thin layer)
2
New cards
Voltage measured between two points
reference electrode - ECF
Recording electrode - ICF
Potential energy measured in mV
Resting membrane potential = 70mV (neurons/muscle fibers)
3
New cards
Due to distribution of ions across membrane
ions important in polarization of neuron
most important
sodium
potassium
Proteins - largely trapped on inside of membrane
Chloride - near equilibrium
