Cell Membrane [This transcript represents the audio included in the video provided by your Professor.] [Professor]: The characteristics of the cell membrane around a neuron are critical to understanding how an action potential is transmitted down the axon of a neuron. The cell membrane allows some molecules freely to pass across the membrane like water, oxygen, carbon dioxide, other substances cannot pass at all under no circumstances and then some substances, specifically ions can pass sometimes but not other times, and ions can pass through the membrane through ion channels and so this is a closed ion channel and you can see these ions cannot pass through and this is an open ion channel and the ions can pass through. There is a
