Question 4 of 10
Question 4: You are charged with designing an
artificial organ that requires all of its cells to
communicate with one another effectively for
proper functioning. What type of cell junction
should you include when designing such an
organ?
Give some introduction about INTERNAL RESISTANCE CELLS
a) How does voltage change over distance from the stimulator on the artificial axon? AND why does this occur? (Think: where is the current going?)
b) How and why are neurons affected by the addition of myelin (think membrane resistance, capacitance, and the length constant)?
