Discuss the function of hair cells as sensory receptors, and identify two different locations and/or

organs that utilize these receptors. What will be an ideal response?


Hair cells are mechanoreceptors that contain a single long kinocilium and numerous short stereocilia.
When the stereocilia are deformed in one direction, depolarization results, and neurotransmitters are
released which stimulate adjacent neurons; when they are deformed in the other direction,
hyperpolarization results. Hair cells are the main mechanoreceptors in the utricle, saccule, the
semicircular canals, and the organ of Corti.
