Conduction occurs along an axon because
A) outflow of K⁺ triggers the adjacent channels to open.
B) inflow of Na⁺ triggers the adjacent channels to open.
C) once Na⁺ enters the cell, the entire membrane depolarizes simultaneously.
D) axonal transport "walks" voltage changes along the membrane.

Question

Quizplus · Accepted Answer

Conduction occurs along an axon because inflow of Na⁺ triggers the adjacent channels to open in a domino-like effect, allowing the electrical signal to propagate down the axon.
