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 neurotransmitter to receptors action potential in synaptic knob postsynaptic 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 …
Question: Sodium Gates In An Axon Open When The Membrane Is Depolarized Beyond A Threshold ( 50 MV). These Sodium Gates Are Examples Of What? Mechano-gated Channels Ligand-gated Channels A Non-gated Channels Voltage-gated Channels
Question: Which Of The Following Is Not A Characteristic Of A Graded Potential? It Occurs When A Stimulus Causes The Opening Of Gated Ion Channels. Its Magnitude Depends On The Strength Of The Stimulus. It Is All-or-none. It Can Summate, If A Second Stimulus Occurs Before The Membrane Returns To Resting First Graded Potential. It Can Be Hyperpolarizing Or Depolarizing….
