plz tell me, why extracellular k increases can cause depolarization in the case of hyperkalemic paralysis, I know the depolarization is caused by inward Na current, meantime the K channel is closed I just began my study so help me

rectifier K+ channels ...... retention of K+ in ICF due ti high K+ outside leads to inc. in intracellular potential.......depolarizaton.! remember K+ has a positive charge......can also result in depolarization if gets retained in addition to influx of Na+!
