Question
Chapter 10, Problem 17RQ
Summary Introduction
Introduction: The energy is carried by the sound waves in the process of hearing. These waves are alternating peaks of compressed air and valleys in which molecules are farther apart. The sound waves are guided to the internal ear by the ear pinna.

Which of the following is true regarding the difference between graded and action potentials?
a.) Action potential occur only when the surface of the neuron is myelinated, but graded potentials occur in both in both myelinated and non-myelinated neurons.
b.) The magnitude of action potential depends on the magnitude of the stimulus, whereas graded potentials are all or none.
c.) The magnitude of graded potential depends on the magnitude of the stimulus, whereas action potentials are all or none.
A graded potential (a) decreases with distance from the point of stimulation. (b) spreads passively because of local currents. (c) may involve either depolarization or hyperpolarization. (d) a, b, and c are correct.
