Uberon definition : The part of the ear that projects from the head, connecting to the external acoustic
meatus.;
Uberon synonym : auricle; pinna of ear; auricle of ear; auricle of external ear; auricula (auris externa); auricula;
Uberon related term : pinnae;
Uberon Function note : The purpose of the pinna is to collect sound. It does so by acting as a funnel, amplifying
the sound and directing it to the ear canal. While reflecting from the pinna, sound
also goes through a filtering process which adds directional information to the sound
(see sound localization, head-related transfer function, pinna notch).;
Uberon Homology note : Mammals have a third type of tympanic ear. An external flap, the auricle or pinna,
helps funnel sound waves down the external acoustic meatus to the tympanic membrane.[well
established][VHOG];
Uberon Taxon note : In various species, the pinna can also signal mood and radiate heat;
