You have been infected by a virus that led to an inflammation of your cochlea and the destruction of inner ear hair cells. This situation would result in _____________________.
Sensorineural hearing impairment
Increased movement of stereocilia towards the kinocilium
Central hearing impairment
Conductive hearing impairment
Loss of endolymph in the cochlear duct
Please consider providing a detailed and elaborate explanation of both correct options and incorrect options.
