Which term means 'Right ear'?

Explanation:
In medical shorthand, regions use Latin roots. The right ear is called auris dextra, with dextra meaning right and auris meaning ear, so it’s abbreviated a.d. This keeps anatomy clear across languages and notes. In contrast, oculus dexter (o.d.) and oculus sinister (o.s.) refer to the eyes—right eye and left eye. A.u. can denote both ears, but when you need a single-ear designation, a.d. is the precise term.
