Which of the following statements best describes the receptor potential?
A)The receptor potential is always constant
B)The greater the intensity of the stimulus, the greater the change in receptor potential
C)Any change in the receptor potential will induce an action potential
D)Receptor excitation always involves depolarization of the receptor

Question

Quizplus · Accepted Answer

The receptor potential is the change in the membrane potential of a sensory receptor cell that results from a sensory stimulus. The greater the intensity of the stimulus, the greater the change in receptor potential, which in turn can lead to the generation of an action potential. Therefore, statement B is the most accurate description of the receptor potential. Statements A, C, and D are not necessarily true in all cases.
