If some excitable tissue is partially depolarized ,should not it be hypeexcitable ,instead of being paralysed ???

if the depolarization is partial the exitability is higher, hence there will be a summation of action potentials and tetany...spastic paralysis of mm

if there is hypokalemia, hyperpol will follow and ........flaccid paralysis
