D) a voltage change must occur

Question

Quizplus · Accepted Answer

Nervous system signals are characterized by their ability to travel quickly, allowing for rapid transmission of signals.

Answer D is also correct to an extent, as a voltage change (action potential) must occur for nervous signals to be transmitted. However, this characteristic alone is not sufficient to distinguish nervous signals from endocrine signals.

Answer A and C are incorrect as they do not accurately describe characteristics of nervous system signals. Gradual changes are more characteristic of endocrine signals, and nervous signals generally have a more localized impact than affecting the entire body.
