Question

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

I have been asked this question in an interview for internship.

The above asked question is from Origin of Bioelectric Signals in section Bioelectric Signal and Electrodes of Biomedical Instrumentation

Answer 1

Correct option is (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.
