4. What is the difference between membrane irritability and membrane conductivity? Membrane irritability is the ability to respond to stimuli and convert them into nerve impulses and conductivity is the ability to transmit an impulse (in this case, to take the neutral impulse and pass it along the cell membrane).
5. Why does the nerve’s action potential increase slightly when add 1.0 V to the threshold voltage and stimulate the nerve?
The action potential increases slightly because the nerve consists of more than one neuron, therefore increasing the voltage increases the number of neurons that are stimulated causing depolarization of most of the neurons
6. If you were to spend a lot of time studying nerve physiology in the laboratory, what type of stimulus would use, and why? If I spent time studying nerve physiology in a lab, I would use electrical stimulus. Using electrical stimulus
7. Why does the addition of sodium chloride elicit and action potential? The addition of sodium chloride elicits and action potential because it increases the concentration of sodium outside of the cell which generates an active transport of sodium into the cell and potassium outside of the cell.
8. What was the effect of ether on elicitation and an action potential? Either blocks nerve transmissions, therefore suppressing the ability of the nerves to elicit an action potential.
9. Does the addition of ether to...
