Title: Explain how the absolute refractory period ensures directionality of action potential propagation. Post by: dkpierce on Jun 19, 2012 I have an assignment due tonight at midnight and I am stuck on these questions, can someone help me PLEASE!!
5-1 Explain how the absolute refractory period ensures directionality of action potential propagation. 5-2: Some tissues (for example, cardiac muscle) have long absolute refractory periods. Why would this be beneficial? 5-3: What do you think is the benefit of a relative refractory period in an axon of a sensory neuron? Title: Explain how the absolute refractory period ensures directionality of action potential propagation. Post by: duddy on Jun 19, 2012 1. A refractory period is when the membrane is less excitable. When local currents develop, the action potential must move forward because the previous section is in the absolute refractory period.
2. A long absolute refractory period ensures that the muscle contracts fully. 3. The benefit of a relative refractory period in an axon of a sensory neuron is that it is easier to modify the intensity of the sensation by altering the frequency of stimulation.
