Neurotoxin
A neurotoxin is a toxin that acts specifically on nerve cells (neurons), usually by interacting with membrane proteins such as ion channels. Some sources are more general, and define the effect of neurotoxins as occurring at nerve tissue. Bungarotoxin, which is considered a neurotoxin, has its effect at the motor end plate.
