question 115

Multiple Choice

Professor Freeman calls on his student Maya to describe how the presence of myelin affects an action potential.Maya should respond with which of the following statements?

• A)Current flows along the unmyelinated segments and action potentials propagate along the myelinated portions of the axon,decreasing the speed and efficiency of the action potential.
• B)Current flows under the myelin and action potentials propagate along the unmyelinated segments of the axon,decreasing the speed and efficiency of the action potential.
• C)Current flows along the unmyelinated segments and action potentials propagate along the myelinated portions of the axon,increasing the speed and efficiency of the action potential.
• D)Current flows under the myelin and action potentials propagate along the unmyelinated segments of the axon,increasing the speed and efficiency of the action potential.
