Multiple Choice

The toxins responsible for most shellfish poisonings are water-soluble,heat and acid-stable,and ordinary cooking methods do not eliminate the toxins.Would you predict saxitoxin to affect myelinated and non-myelinated neurons equally?

A) Yes, because all neurons have Na⁺ transporters
B) No, because saxitoxin will not be able to diffuse through the myelin
C) Yes, because saxitoxin works at the synapses of neurons, and thus would be able to access both types of neurons equally
D) No, because myelinated neurons have a smaller Na⁺ gradient, and thus will be more resistant
