P​​redict the effect that tetrodotoxin would have on Albert's muscle fiber action potentials (see question 3). Would it affect end-plate potentials at the motor end plate? Why or why not? (Connects to Chapter 10)

Video transcript

Hey, everyone. Let's take a look at this question together. How would a neurotoxin like those found in snake venom affect nerve impulses. Is it answer choice. A? They interfere with nerve impulses. Answer choice B, prolong nerve impulse duration, answer choice C, both answer choices A and B or answer choice D, none of the above. Let's work this problem out together to try to figure out which of the following answer choices best explains how a neurotoxin would affect nerve impulses. So in order to solve this question, we have to recall what we have learned about neurotoxins like the neurotoxins found in snake venom and how they affect nerve impulses. And we can recall that snake neurotoxins primarily affect the neuromuscular junction by causing a disruption to neurotransmission of which that disruption to neurotransmission results in paralysis of the skeletal muscles. As well as the majority of snake venom neurotoxins, either affect the motor nerve terminals of the presynaptic neuron or the nicotinic acetylcholine receptors of the post synaptic neurons. So looking at our answer choices, which of the following best explains how the neurotoxins affect nerve impulses. And we can identify answer choice. A that they interfere with nerve impulses is the correct answer and answer choices. BC and D are all incorrect. I hope you found this video to be helpful. Thank you and goodbye.
