Septum of musculotubal canal
Septum canalis musculotubarii
- Latin synonym: Septum canalis musculotubalis
Definition
The septum of musculotubal canal, formally known as the septum canalis musculotubarii or processus cochleariformis, is a critical bony structure within the temporal bone of the skull that plays a key role in dividing the musculotubal canal into two distinct semicanals. The first semicanal, located superiorly, is designated for the tensor tympani muscle (semicanalis m. tensoris tympani), while the second, positioned inferiorly, forms the bony part of the auditory tube (semicanalis tubae auditivae).
