- Pinna
- External auditory canal (secretes cerumen)
- Tympanic Membrane
- Tympanic Membrane (chorda tympani branch of facial nerve carrying taste from front of tongue, traverses the pars flaccid of TM then over the neck of the malleus)
- Tympanic cavity (epimesohypotympanum)
- Ossicles (malleus, incus, stapes)
- Eustachian tube
- Mastoid air cells (aerated by middle ear as SCM pulls on it)
