Question: Match each description to the appropriate refractory period. Absolute refractory period Relative refractory period Answer Bank A stronger than normal stimulus is needed to initiate an action potential. Sodium channels are inactivated. Sodium channels finish resetting. Potassium channels begin to close. Sodium influx occurs.
Question: QUESTION 8Which of the following is/are true of the absolute refractory period?Na+ channel inactivation is responsible for the absolute refractory period.The absolute refractory period is the time during which another stimulus given to the cell (no matter how strong) will not lead to a second action potential.The absolute refractory period precedes the
During the absolute refractory period the cell A. generates many local potentials B. is insensitive to further stimulation C responds to even weak stimuli. D reverses the direction of the action potential. E. is very sensitive. Gap junctions are functional ____ synapses. A. chemical B. electrical C. potential D. intracellular E. neuromuscular

Part A. Which of the following correctly completes the sentence? The period of time after an action potential when another. action potential cannot be generated is the. relative refractory period. absolute refractory period. repolarization period. hyperpolarization period. Here’s the best way to solve it.
Question: Which of the following is TRUE regarding the refractory period? Select all that apply.Group of answer choicesduring the relative refractory period Na+ inactivation gates are closedthe refractory period prevents action potentials from propagating along a membrane in two directionsthe refractory period begins when a stimulus is applieda new action potential
Explain how the absolute refractory period ensures directionality of action potential propagation. Here’s the best way to solve it. Solution. 100% (1 rating) Ans. The absolute refractory period ensures directionality of action potential propagation.Because after that period the action potential has to move forward and can't generate another ...
Anatomy and Physiology questions and answers. Question 20 A segment of the axon enters its absolute refractory period when and leaves is absolute refractory period when the voltage-gated Nat channels open the voltage-gated K channels close the voltage-gated Nat channels open the voltage-gated Na channel activation gates close the inactivation ...
Answered by. Anatomy and physiology expert. 2. Refractory Period : The nerve cannot respond to a second stimulus during much of the action potential and even longer. This is referred to as the refractory period of the nerve. In fact, the refractory period is further divided into an absolute re …. View the full answer.
Question: The refractory period is associated with voltage-gated potassium channels. During this refractory period another action potential can be generated. Multiple Choice absolute negative relative. There are 2 steps to solve this one. Step 1.
