C)equilibrium
D)vision
E)touch

Question

Quizplus · Accepted Answer

Olfactory receptor cells directly produce action potentials in response to odorants binding to their receptors. The other sense receptor cells (in hearing, equilibrium, vision, and touch) require intermediate cells or structures to convert their stimuli into graded potentials before producing action potentials in the downstream neurons.
