Nerve Impulses

LAB THREE: Neurophysiology of Nerve Impulses

In step-up to the science lab report assignment, you must answer the following questions after finish the lab. Submit your assignment to the Week 3 Dropbox by no later than Sunday, end of week 3, 11:59 P.M. (MT).


1. wherefore dont the terms depolarization and bodily process potentiality drop mean the same thing? (6 points)


A depolarization is whatsoever change in a neuron that makes it more substantiating than resting potential, an action potential only occurs when the depolarization reaches the threshold level.



2. What is the variation between membrane irrit magnate and membrane conductivity? (6 points)

mood is the ability to respond to stimuli and convert it to nerve impulses; conductivity is the ability to actually transmit an impulse.

3. wherefore does a nerves action potential increase slightly when you add 1.0 V to the threshold voltage and stimulate the nerve? (6 points)


The action potential increases because the nerve consists of more than one neuron, when you increase the voltage it increases the rate of neurons that are stimulated causing depolarization of most of the neurons

4. If you were to knock off a lot of time studying nerve physiology in the laboratory, what type of stimulus would you use, and why?



(6 points)


I would use chemical stimulation. I would want to see what polar chemicals would cause an action potential vs chemicals that would not cause an action potential and whether different amounts of a particular chemical would affect the action potential.

5. Why does the addition of sodium chloride elicit and action potential? (6 points)

it increases the submergence of sodium outside of the cell which generates an active transport of sodium into the cell and potassium outside of the cell.

6. What was the effect of ether on eliciting an action potential? (6 points)

There was no effect it conducted the same

7. Does the addition of ether to the...If you want to get a full essay, drift it on our website: Ordercustompaper.com
