11. If injected a toxin that blocks voltage gated sodium channels what will be observed

when looking at action protentional of a neuron? what does this mean for

neurotransmitter release? Will the end plate still be activated? If this is the

neuromuscular junction will a contraction still occur?

12. What would occur if a toxin was injected and blocked voltage gated K+ from opening?

13. What would occur if you tried to simulate the neuron during the absolute refractory

period vs relative refractory period?

14. Who would have a higher conduction velocity a neuron with myelin or without myelin

and why?

15. Drug A was just made and it is full of acetylcholinesterase and goes into the synaptic

cleft of the neuromuscular (NMJ). What is likely to occur at NMJ? Does the presynaptic

terminal still generate action protentional? What will mostly likely occur at post synaptic

terminal? Can you generate contraction? At the Post synaptic membrane what ions are

affected?
