Resting membrane potentials in nerve/muscle cells

Does anyone know what the difference in resting membrane potentials between muscle and nerve cells please?

Getting stressed!

Thanks very much xxx

nevre cells have a negative charge and outside the cell there is a positive charge and thats the resting potential.. i think i'm right but tbh i'm a bit hazy...

hmmm but what is the difference? thanks

Depends on the neurone, and what's happening to it e.g. in long term potentiation (LTP) these things are liable to change. It also depends on what type of muscle you're talking about (e.g. cardiac pacemaker cells have a constantly changing resting potential, due to their special slow inwards sodium channels). Be more specific.
