pharyngotympanic tube

Organ with organ cavity which connects the cavity of the middle ear to the cavity of the pharynx. Examples: There are only two pharyngotympanic tubes, the right and the left pharyngotympanic tubes.[FMA]. Every claim on this page comes from the Leumas anatomy graph and carries its source.

Questions

Where is the pharyngotympanic tube?

It sits in the head, within the sensory system. Positioned deliberately as part of this species body plan.

What does the pharyngotympanic tube connect to?

Part of: middle ear.
