Ear structure which contains hair nerve cells
WebMeanwhile, hair cells inside the cochlea are being pushed back and forth, and that transmits an electrical impulse via this auditory nerve to the brain. The reason that the fluid doesn't move back to the oval window when it goes to the very tip of the cochlea is because in between, in the very middle of the cochlea, is a membrane. WebThe saccule is a bed of sensory cells in the inner ear. It translates head movements into neural impulses for the brain to interpret. The saccule detects linear accelerations and head tilts in the vertical plane. When the head moves vertically, the sensory cells of the saccule are disturbed and the neurons connected to them begin transmitting ...
