Action potentials are related to impulses conducted along an axon in that A) many impulses are required to cause one action potential. B) active transport of Na⁺ and K⁺ are required for impulse conduction but not for an action potential. C) impulses are stronger responses than are action potentials. D) propagation of a series of action potentials along a nerve cell fiber constitutes an impulse.

Question

Quizplus · Accepted Answer

Propagation of a series of action potentials along a nerve cell fiber constitutes an impulse. Impulses are the result of multiple action potentials traveling down the length of the axon in succession, allowing for the transmission of signals over long distances. Active transport of Na+ and K+ ions is necessary for both impulse conduction and the generation of action potentials.
