Action Potential Simulation - Guided Inquiry Activity - PhET

WebAs the action potential passes through, potassium channels stay open a little bit longer, and continue to let positive ions exit the neuron. This means that the cell temporarily hyperpolarizes, or gets even more negative than its resting state. As the potassium channels close, the sodium-potassium pump works to reestablish the resting state. ... WebThe action potential then propagates without decrement to adjacent membranes due to the opening of gap junctions between adjacent cells, allowing electrical current to pass through. Answer 2: The sensory system encodes the location of a stimulus, its modality, and its intensity level. For example, the position of receptors on the body, such as ... primetime healthcare nebraska
