Cochlea (The Senses) Mini Quiz
Test your knowledge with these top questions!
What does the cochlea convert into electrical signals for the brain?
Hair cells in the organ of Corti turn sound-driven mechanical motion into electrical signals carried by the auditory nerve.
Which cochlear structure houses the sensory hair cells for hearing?
The organ of Corti rests on the basilar membrane and contains inner and outer hair cells that detect vibrations.
Which fluid bathes cochlear hair-cell stereocilia?
Endolymph fills the cochlear duct and bathes the stereocilia; its high potassium concentration helps hair cells generate receptor potentials.
Where does the cochlea respond most strongly to high-frequency sounds?
The basilar membrane is stiff and narrow at the base, so high frequencies peak there; low frequencies peak near the wider, flexible apex.
