  2. Eustachian tube - Wikipedia

    en.wikipedia.org/wiki/Eustachian_tube

    The Eustachian tube (/ j uː ˈ s t eɪ ʃ ən /), also called the auditory tube or pharyngotympanic tube, [1] is a tube that links the nasopharynx to the middle ear, of which it is also a part. In adult humans, the Eustachian tube is approximately 35 mm (1.4 in) long and 3 mm (0.12 in) in diameter. [ 2 ]

  3. Middle ear - Wikipedia

    en.wikipedia.org/wiki/Middle_ear

    The hollow space of the middle ear is also known as the tympanic cavity and is surrounded by the tympanic part of the temporal bone. The auditory tube (also known as the Eustachian tube or the pharyngotympanic tube) joins the tympanic cavity with the nasal cavity (nasopharynx), allowing pressure to equalize between the middle ear and throat.

  4. Ear - Wikipedia

    en.wikipedia.org/wiki/Ear

    The ear canal of the outer ear is separated from the air-filled tympanic cavity of the middle ear by the eardrum. The middle ear contains the three small bones—the ossicles—involved in the transmission of sound, and is connected to the throat at the nasopharynx, via the pharyngeal opening of the Eustachian tube.

    Finally, the Eustachian tubes' apertures are located slightly above the soft palate and in the nasal cavity. These small tubes connect the upper pharynx (also known as the nasopharynx) to the middle ear and are essential for equalization. [8]

  7. Tympanic nerve - Wikipedia

    en.wikipedia.org/wiki/Tympanic_nerve

    The tympanic nerve (Jacobson's nerve) is a branch of the glossopharyngeal nerve passing through the petrous part of the temporal bone to reach the middle ear.It provides sensory innervation for the middle ear, the Eustachian tube, the parotid gland, and mastoid cells.

  8. Auditory system - Wikipedia

    en.wikipedia.org/wiki/Auditory_system

    Auditory ossicles from a deep dissection of the tympanic cavity. Sound waves travel through the ear canal and hit the tympanic membrane, or eardrum. This wave information travels across the air-filled middle ear cavity via a series of delicate bones: the malleus (hammer), incus (anvil) and stapes (stirrup).

  9. Tubal tonsil - Wikipedia

    en.wikipedia.org/wiki/Tubal_tonsil

    Each tubal tonsil is located posterior to the opening of the Eustachian tube on the lateral wall of the nasopharynx. [1] It is one of the four main tonsil groups forming Waldeyer's tonsillar ring. [2] This ring also includes the palatine tonsils, the lingual tonsils, and the adenoid. [2]
