Question

After a cell is stimulated, a finite period of time is required for the cell to return to its pre-stimulus state. This period is known as ____________

(a) restoration period

(b) refactory period

(c) regain period

(d) regenerative period

This question was posed to me in an internship interview.

This is a very interesting question from Origin of Bioelectric Signals in division Bioelectric Signal and Electrodes of Biomedical Instrumentation

Answer 1

Correct answer is (b) refactory period

The explanation is: After a cell is stimulated, a finite period of time is required for the cell to return to its pre-stimulus state. This is because the energy associated with the action potential is developed from metabolic process within the cell which takes time for completion. This time period is called refactory period.
