Which statement regarding conduction is true?

The statement that orthodromic conduction is in a physiological direction while antidromic conduction is not is accurate because it reflects the typical flow of action potentials in neurons. Orthodromic conduction refers to the natural propagation of an action potential along a neuron from the cell body toward the axon terminals. This is the normal direction of signal transmission in a physiological context, allowing for effective communication between neurons and their target tissues.

Antidromic conduction, on the other hand, occurs when the action potential travels in the opposite direction, from the axon terminal back to the cell body. This is not the typical physiological direction for nerve impulses, and while it can be induced experimentally—such as during certain types of nerve stimulation—it doesn't represent the normal functional pathway used for transmitting signals within the nervous system.

Understanding these differences is vital for interpreting nerve conduction studies and the functional characteristics of neurons. The other statements do not accurately reflect the established electrophysiological principles governing nerve conduction patterns.
