You measure the membrane potential and find that it does not change from time X to time Y. However, you find that current across the membrane has increased by a factor of 4 from time X to time Y. Which of the following most likely happened between time X and Y? a. 4 times as many ion channels closed on the cell membrane b. Resistance of the membrane changed to ½ c, Resistance of the membrane changed to ¼ d. not enough information

Why is it used as a model for neuroinflammation? Describe microglia: where are they found, what role do they play, why can't that role be carried out the same way it is in the rest of the body? Mitofusin2 (Mfn2) is a mitochondrial protein. What is its apparent role? Can you think of a reason why overexpression could be protective against a stress? Is it reasonable that overexpression of this gene could also cause problems (if so, how)? How did the authors arrange that Mfn2 was only upregulated in the brain and spinal cord of TMFN mice, and not in other tissues of the mice? How do they demonstrate this?

Fil in the blanks 1. A resting muscle fiber or neuron has an internal charge that is A. positive, B. negative, or C. neutral compared to the extracellular environment. This resting membrane charge is maintained by the A. calcium ion channels, B. sodium voltage gates, C. potassium voltage gates, or D. sodium/potassium pumps? . When a muscle fiber is at resting membrane potential there is a(an) "higher", "equal", OR "lower" concentration of sodium inside the cell compared to outside the cell and a(an) "higher", "lower", OR "equal" concentration of potassium inside the cell compared to outside.
