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
