An organ composed mainly from epithelial and nervous tissues converts vibrations into impulses that are sent to the brain. Which organ could this be?

The movement of the eardrum causes the bones of the middle ear (the ossicles) to vibrate. These vibrations then pass into the cochlea, the organ of hearing. Within the cochlea, the hair cells on the sensory epithelium of the organ of Corti bend and cause movement of the basilar membrane.
