External Ear

3.Tympanic Membrane: Impulses from external ear move through the Tympanic Membrane (Ear Drum) to the Malleus.

2.External Acoustic Meatus: Ear Canal that carries sound to the Tympanic Membrane.

1.Auricle: Collects sound waves traveling through the air, directs them into the External Acoustic Meatus. images

10.Cochlear Duct:Vibrations enter the endolmph of the Basilar Membrane.

11.Basilar Membrane:Vibrations move through the Basilar Membrane.

13.Scala Tympani: Vibrations enter the perilymph of the Scala Tympani and their forces dissipate into the air.

12.Organ of Corti:The hair cells convert vibrations into nerve impulses that are transmitted by the cochlear portion of the eight cranial nerve to the brain.

14.Round Window:Vibrations exit through the round window. images (7)
