Raven Johnson Biology Chapter 48 Answers to Review Questions 1.
Sensory transduction is the transmission of a sensory nervous impulse.
A receptor potential is a change in membrane potential that occurs in a sensory receptor. Otoliths in the saccule and utricle of the inner ear respond to changes in body position relative to gravity. The semicircular canals in the inner ear detect changes in angular acceleration. There are three to detect changes in all three dimensions perpendicular to one another. This works as long cilia of sensory cells move against short cilia in the same direction as fluid moves, altering firing of neurons of short cilia.
