Document Summary

Pinna flesh covered cartilage attached to the side of the head. Helps funnel sound through the ear canal toward the middle and inner ear. Flexible membrane that vibrates back and forth in response to sound waves and passes these vibrations on the receptor cells in the inner ear. Ossicle one of the 3 bones in the inner ear. Cochlea a snail shaped chamber set in bone in the inner ear where auditory transduction takes place. Basilar membrane a sheet of tissue that contains the auditory receptor cells. Auditory hair cells transduce mechanical energy caused by the flexing of the basilar membrane into neural activity. An opening in the bone surround the cochlea. Movements of the membrane behind this opening permit vibrations to be transmitted through the oval window into the cochlea. A hair like appendage of cell involved in the movement of sensory information found in the receptors in the auditory and vestibular systems.
