(the external auditory meatus) that directs sound waves on to the tympanum, and may
also include the external pinna, which extends beyond the skull[GO].;
Uberon synonym : auricular region of head; outer ear;
Uberon related term : auris externa;

the tympanic membrane which is considered to be an ear canal and thus an outer ear.
(...) The ancestral lineage of amphibians separated from the mammalian lineage, approximately
350 million years ago, in the paleozoic era. Many of the important developments in
the auditory systems emerged after the ancestral paths separated (Manley and Clack
2003). This implies that shared features, like the tympanic middle ear, developed
independently in different vertebrate lineages.[uncertain][VHOG];
