Ear canal

from Wikipedia, the free encyclopedia
Drawing of the outer ear of man

As meatus two are ear extending passages in terrestrial vertebrates designated. A distinction is made between an outer and an inner auditory canal ( Meatus acousticus externus and internus ). The outer ear canal is used to conduct sound from the outside world to the eardrum . The internal auditory canal is used for the passage of the vestibulocochlear nerve .

The inner ear is complete, the external auditory canal only partially bony supported. The bony sections belonging to the skull - more precisely to the temporal bone - are called the ear canal ( Canalis acusticus externus or internus ), the opening of which is called Porus acusticus externus or internus .
