Which of the Following is True of Axons

Question

Which of the following is true of axons?
A)contain receptive areas
B)very thin and short
C)originates at the axon hillock on the cell body
D)transmits graded electrochemical impulses

Accepted Answer

Axons originate at the axon hillock on the cell body.

Answer: D
 Axons transmit action potentials, which are all-or-nothing electrochemical impulses, rather than graded electrochemical impulses. A graded potential occurs when the membrane potential of a neuron changes in response to a stimulus, but the change is not large enough to lead to an action potential.
