why partial agonist is unable to reach the maximal response?

A toxin found in shellfish blocks voltage-gated Na+ channels from opening in somatic motor neurons. What effect would this have on nerve and muscle function?

Neurons wouldn’t depolarize; muscle would contract continuously (spastic paralysis)

Neurons wouldn’t repolarize; muscle would be unable to contract (flaccid paralysis)

Neurons wouldn’t repolarize; muscle would contract continuously (spastic paralysis)

Neurons wouldn’t depolarize; muscle would be unable to contract (flaccid paralysis)

Neurons wouldn’t depolarize, but this would not affect muscle function
