The relationship between the temporal bone and the ear?
The petrous part of the temporal bone encloses the structures of the inner ear. Inside the tympanic cavity within the petrous part is the middle ear. The external acoustic canal ends at the tympanic membrane, which leads to the inner ear. Mastoid air cells within the mastoid process are connected to the tympanic cavity.
Site of styloid process?
