Part 1: Modeling Passive Transport Explain why the resistance of the current path through the extracellular fluid is much smaller than the resistance of the current path through the axoplasm. Extracellular fluid membrane axoplan membrane Extracellular fluid (Fig 3) Axon: Simple cylinder model A long axon can be modeled as a chain of many short segments like the segment described above. The dashed lines in Figure 4 below visually divide the axon into five such segments. Sketch the path of current flow onto the diagram and then design a circuit model for it. Check your model with your instructor. (Fig 4) Axon: chain of many segments Use the relationship between resistance, resistivity, length, and cross-sectional area to estimate values for the resistances of a membrane segment Reem and an axoplasm segment Reson.
