Question

In the organ of Corti, identify the major conductance responsible for auditory transduction at the stereocilia, which will cause depolarization of a hair cell.

Select one:

a. An outward Na⁺ current

b. An inward Na⁺ current

c. An outward K⁺ current

d. An inward K⁺ current

Answer 1

D is correct answer because k+ concentration is low hair cell and more in endolymph which surround hair cell. So k+ move from fluid to hair cell cause depolarization of hair cell.
