描述

At the angle of junction of the petrous part and the squama are two canals, one above the other, and separated by a thin plate of bone, the septum canalis musculotubarii (processus cochleariformis); both canals lead into the tympanic cavity. The upper one, the canal for tensor tympani (semicanalis m. tensoris tympani) transmits the Tensor tympani, the lower one, the canal for auditory tube (semicanalis tubæ auditivæ) forms the bony part of the auditory tube.
