Title: What is the effect of lidocaine on the generation of AP? Explain why. Post by: jc9193 on Jun 24, 2013 Activity 2
1) Can hyperpolarized graded potential lead to an AP in the axon terminal? Explain why. Activity 3 2) Did a stimulus stronger than threshold cause an AP of higher amplitude? Answer: Activity 4 3) What is the effect of lidocaine on the generation of AP? Explain why. Answer: Blocks voltage- gated Na+ channels. Hard to reach, reduces further potential.( I'm not 100 percent sure of this answer) Activity 6 4) Stimulus voltage of 30 mV generated an AP frequency of Hz; stimulus voltage of 45 mV generated an AP frequency of Hz. Answer: 0.161 and Activity 7 5) Which of the three nerves had the fastest conduction velocity? Explain why. Answer: A fiber ; thick, heavy myelinated , larger diameter and propagate faster.

Title: What is the effect of lidocaine on the generation of AP? Explain why. Post by: robertling on Jun 25, 2013 Activity 4 3) What is the effect of lidocaine on the generation of AP? Explain why. Answer: Blocks voltage- gated Na+ channels. Hard to reach, reduces further potential.( I'm not 100 percent sure of this answer) Calcium channels could possibly substitute for sodium channels to provide an influx of cation.
