Which of the following statements about the action potential is FALSE ? A. The action potential lasts about four milliseconds. B. It is triggered by anions crossing the cell membrane. C. The sequence: ‘Na ions moving in, K ions moving out’ constitutes the action potential. D. Repolarisation follows depolarisation of the cell membrane.
Option B. Anions ( ve ions) crossing the membrane is the first a part of the action potential , however this movement is brought on through a graded ability that is above threshold arriving on the begin of the axon (the axon hillock).
