Auditory Tube

The Eustachian tube (also auditory tube or pharyngotympanic tube) is a tube that links the nasopharynx to the middle ear. It is a part of the middle ear. In adult humans the Eustachian tube is approximately 35 mm long. It is named after the sixteenth-century anatomist Bartolomeo Eustachi. Some modern medical books call this the pharyngotympanic tube [Wikipedia: http://en.wikipedia.org/wiki/Eustachian_tube].
