| 单词 | resting potential |
| 例句 | Up to 50 percent of a neuron’s ATP is used in maintaining its membrane resting potential. Concepts of Biology 2013-04-25T00:00:00Z Now, if the exterior of a neuron is taken to be at 0 V, then the interior has a resting potential of about –90 mV. College Physics for AP Courses 2015-08-12T00:00:00Z The diffusion of K+ out of the cell actually hyperpolarizes the cell, in that the membrane potential becomes more negative than the cell's normal resting potential. Biology for AP Courses 2022-06-09T00:00:00Z Repolarization returns the membrane potential to the -70 mV value that indicates the resting potential, but it actually overshoots that value. Anatomy and Physiology 2013-06-19T00:00:00Z A sharp tap was now given to the stalk, and a sudden diminution, or negative variation, of current occurred, the resting potential difference being decreased by ·026 volt. Response in the Living and Non-Living K+ ions continue to leave the cell and the membrane potential returns to the resting potential. Concepts of Biology 2013-04-25T00:00:00Z The depolarization causes the membrane to again become impermeable to Na+ , and the movement of K+ quickly returns the cell to its resting potential, or repolarizes it. College Physics for AP Courses 2015-08-12T00:00:00Z The actions of the sodium potassium pump help to maintain the resting potential, once established. Biology for AP Courses 2022-06-09T00:00:00Z Then the channel closes again and the membrane can return to the resting potential because of the ongoing activity of the non-gated channels and the Na+/K+ pump. Anatomy and Physiology 2013-06-19T00:00:00Z The resting potential is the state of the membrane at a voltage of -70 mV, so the sodium cation entering the cell will cause it to become less negative. Anatomy and Physiology 2013-06-19T00:00:00Z At the resting potential, the K+ channels close and Na+ channels reset. Concepts of Biology 2013-04-25T00:00:00Z Unlike skeletal muscles and neurons, cardiac conductive cells do not have a stable resting potential. Anatomy and Physiology 2013-06-19T00:00:00Z Once depolarization is complete, the cell must now "reset" its membrane voltage back to the resting potential. Biology for AP Courses 2022-06-09T00:00:00Z For a membrane at the resting potential, a graded potential represents a change in that voltage either above -70 mV or below -70 mV.
