Q.

The variation of the electrical potential associated with the passage of a pulse along the membrane of a muscle cell or a nerve cell is called                      

A. muscle potential
B. action potential
C. resting potential
D. half cell potential
Answer» B. action potential
Explanation: An action potential occurs when the potential of the membrane of a given axonal position increases and decreases rapidly. This depolarization causes depolarization of adjacent positions in a similar way. Resting membrane potential or the resting potential is the relative static membrane potential of a quiescent cell.
