Stimuli alter the activity of excitable sensory cells and generate action potentials via _____.

TRANSDUCTION. This refers to the stimulus being converted into an action potential which is then transmitted in the axons going to the central nervous system. This usually starts at the receptor cell. The stimulus change the electrical potential across the cell membrane.
