outer ear   (ou'tər)  Pronunciation Key 
The part of the ear in many vertebrates that is external to the eardrum (tympanic membrane) and contains the canal leading to the eardrum as well as the ear lobe and other visible structures. In mammals, the outer ear, which is made mostly of cartilage, gathers and focuses incoming sound waves and transmits them to the eardrum. See more at ear1.
