auditory tube, in terrestrial vertebrates, the canal that unites the pharynx with the cavity of the middle ear; named for B. Eustachio, who first described it in 1563. The eustachian tube serves to equalize the air pressure in the middle ear with that of the surrounding environment. It originates from the rudiment of the gill slit. The Eustachian tube, also known as the pharyngotympanic tube or auditory tube, is the channel via which the tympanic cavity communicates with the nasopharynx. Gross anatomy It is ~36 mm in length and is directed downward, forward, and medially, forming an angle of about 45 degrees with the sagittal plane and one of 30 to 40 degrees with the horizontal plane. This tube is also called the otopharyngeal tube (because it connects the ear to the pharynx) and in medical Latin it is the tuba acustica, tuba auditiva, or tuba auditoria. The pharynx is subdivided into 3 parts: the upper part called the nasopharynx, the middle part called the oropharynx, and the lower part called the hypopharynx.
