Answer
water currents cause the cilia within the gelatinous membrane tobend which causes a nerve impulse to go to the brain
sound waves cause the cilia within the gelatinous membrane to bendwhich causes a nerve impulse to go to the brain
a chemical signal will cause the cilia within the gelatinousmembrane to bend which causes a nerve impulse to go to thebrain
water currents cause a nerve impulse to go directly to thebrain
a chemical signal will cause a nerve impulse to go directly to thebrain
