external ear in dogs

Part of the ear external to the tympanum (eardrum). It typically consists of a tube (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]. Every claim on this page comes from the Leumas anatomy graph and carries its source.

What the external ear is

Part of the ear external to the tympanum (eardrum). It typically consists of a tube (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]. The atlas records it as a region at the region scale in the dog.

Where the external ear is

It sits in the head, within the sensory system. Not positioned individually. Drawn inside the structure this dataset says contains it — the containment is asserted, the exact spot within it is not.

What the external ear connects to

The atlas records 21 typed relationships for it, across 8 kinds of connection. part of anatomical entity, ear and head.

Supply and innervation
