Hair Cell

Hair Cell

Hair cells are the sensory receptors of both the auditory system and the vestibular system in all vertebrates. In mammals, the auditory hair cells are located within the organ of Corti on a thin basilar membrane in the cochlea of the inner ear. They derive their name from the tufts of stereocilia that protrude from the apical surface of the cell, a structure known as the hair bundle, into the scala media, a fluid-filled tube within the cochlea. Mammalian cochlear hair cells come in two anatomically and functionally distinct types: the outer and inner hair cells. Damage to these hair cells results in decreased hearing sensitivity, i.e. sensorineural hearing loss.

Famous quotes containing the words cell and/or hair:

    Why inspire in us a horror of our being?... To look upon the universe as a prison cell and all men as criminals about to be executed is the idea of a fanatic.
    Voltaire [François Marie Arouet] (1694–1778)

    The departing year:
    from my parents I have kept
    my grey hair hidden.
