Question
getind of potassium channel, which increases the "leak" current of potassium. However, it doesn't affect rics can iDelpoaa thm and produce but some The anesthetic binds to and opens a se-gated potassium channels. This inhibits the neurons, and therefore you aren't conscious of the voltage-ga performing the procedure. Amazing!" ned again, but not from pain this time. Cole was undoubtedly right but he sounded like a textbook ad the stuff worked. Now when can I go home?" .At resting membrane potential, why does a small amount of sodium leak into the cell instead 2. Define depolarization and hyperpolarization and their relationship to threshold. 3. Kevin is conscious when certain neurons in his brain are active-they depolarize and undergo action potentials. Describe the process of depolarization of a neuron to threshold. 4. What does Cole mean when he says that anesthesia "inhibits the neurons?" If the anesthesia opens more potassium leak channels, why are Kevin's neurons less likely to produc action potentials? 5.Explanation / Answer
1. At resting membrane potential conductance of Sodium increases and they leak out for the depolarisation of the neuron to - 55mV.
2. Depolarisation is the increasing the membrane potential to - 55 mV from the resting potential and Hyperpolarisation is the decreasing the of membrane potential to - 90mV from - 70mV.
3. Threshold depolarisation potential is the potential must be aquired to generate action potential by influx of sodium ions through open voltage gated sodium channels. It is nearly - 50 to - 55 mV.
4. Anesthetic agents stop the nerve impulses by binding and inhibiting tge Sodium channels and does not maintain the threshold voltage for generation of action potential and inhibits the neurons.
5. More will be the potassium ion ieak channel open more will be the membrane Hyperpolarised and can't attain threshold voltage for generation of action potential.
