Multiple sclerosis is a disease in which myelin is degraded. What aspect of the action potential does this affect? Opening and closing of Na channels is impaired Production of the action potential at the axon hillock can no longer occur Continuous conduction can no longer occur Saltatory conduction can no longer occur Opening and closing of K channels is impaired

Question: 1. 2. 3. Give 3 Examples Of Stimuli That Can Cause A Graded Potential How Are They “connected To The Voltage Gated Channels Of The Axon? What Do We Call The Region Of The Cell Where The Soma Transitions Into The Axon? Axon Hillock How Does The Triggering Of 1 Voltage Gated Channel Affect The Next/adjacent Channels Of The Axon? How Does This Sequential …
Question: Which Channels Are Open At Rest, In A Nerve Cell? Choose One Best Available Answer Voltage-gated Na+ Channels Light-activated Channels Resting Membrane Potential Channels Leak K+ Channels Voltage-gated K+ Channels Ligand-gated Non-selective Channels Ligand Gated K+ Channels Voltage-gated Ca2+ Channels
Question: If You Artificially Stimulate The Center Of An Axon, Action Potentials Are Propagated In Both Directions. Normally, Action Potentials Start At The Axon Hillock And Are Only Propagated Anterograde Towards The Axon Terminal. Explain Why Retrograde Propagation Of Action Potentials Does Not Occur In Vivo. Include Diagrams To Support Your Explanation.
Question: Question 35 (4 Points) Arrange The Following Events That Occur At A Single Synapse In The Correct Order. Assume Only One Action Potential Occurs In The Presynaptic Neuron. (Hint: Begin With Action Potential In Synaptic Knob As #1) Neurotransmitter Release Opening Of Synaptic Knob Ca++ Channels > Opening Of Chemically Gated Ion Channels > Binding Of …
Question: 120 100 2 5 PAN 8 Vontrolar Volume) 9 ECG Heart SOUS 13 51 10 10 2 1D To 2 6 Time) This Figure Shows The Events Of The Cardiac Cycle. What Does “4” Represent? A. Aortic Valve Opening B. Aortic Valve Closing C. AV Valve Opening D. AV Valve Closing E. Both Aortic And AV Valves Opening
Question: Question 36 The Causes The Initial Depolarization Of The Gustatory Cell For A Closing Of Na+ Channels; Salty Taste B Release Of Ca2+ From Endoplasmic Reticulum; Salty And Sour Tastes Influx Of Extracellular Ca2+, Salty And Sour Tastes Opening Of Extracellular Ca2+ Channels: Bitter Taste E Closing Of K+ Channels; Sweet And Umamitastes
Question: What Affects The Velocity Of An Action Potential Down The Length Of An Axon? Choose All That Apply. Strength Of The Graded Potential Amount Of Myelination Axon Diameter Speed Of Na Channels Closing All Action Potentials Are Of The Same Velocity, Regardless Of Which Neuron Is Firing
Question: 1. Describe Why An Action Potential Would Only Travel One Direction, From An Axon Hillock Towards The Axon Terminal. In A Laboratory, A Scientist Could Stimulate A Neuron At Any Place By Applying Voltage Through A Stimulator (for Reference, Think Exceptionally Tiny Cattle Prod). If A Scientist Stimulated An Axon Above Threshold, Halfway Between The …
Question: When The Internal Charge Reaches The Threshold, The Action Potential Begins. Which Channels Open: Ligand-gated Channels Or Voltage-gated Channels? What Enters Through The Channels At This Stage Of The Action Potential?
Question: QUESTION 12 Put The Events Involved In A Chemical Synapse In The Right Order. _ Ion Channels Open, Leading To A Local Potential And Possibly An Action Potential. _ Influx Of Ca_+ Causes Synaptic Vesicles To Release Neurotransmitters Into The Synaptic Cleft. _ An Action Potential In The Presynaptic Neuron Triggers Ca_+ Channels In The Axon Terminal To …
