    On its lateral wall is the pharyngeal opening of the auditory tube, somewhat triangular in shape and bounded behind by a firm prominence, the torus tubarius or cushion, caused by the medial end of the cartilage of the tube that elevates the mucous membrane. Two folds arise from the cartilaginous opening:

  3. Torus tubarius - Wikipedia

    en.wikipedia.org/wiki/Torus_tubarius

    The torus tubarius is situated behind the pharyngeal orifice of the auditory tube. [ 1 ] The torus tubarius is very close to the tubal tonsil , [ 1 ] which is sometimes also referred to as the tonsil of (the) torus tubarius . [ 2 ]

  4. Parapharyngeal space - Wikipedia

    en.wikipedia.org/wiki/Parapharyngeal_space

    The parapharyngeal space (also termed the lateral pharyngeal space), is a potential space in the head and the neck. It has clinical importance in otolaryngology due to parapharyngeal space tumours and parapharyngeal abscess developing in this area. It is also a key anatomic landmark for localizing disease processes in the surrounding spaces of ...

    en.wikipedia.org/wiki/Salpingopharyngeus_muscle

    It is innervated by vagus nerve (cranial nerve X) via the pharyngeal plexus. It raises the pharynx and larynx during deglutition (swallowing) and laterally draws the pharyngeal walls up. It opens the pharyngeal orifice of the Eustachian tube during swallowing to allow for the equalization of pressure between it and the pharynx.

  6. Pharyngeal recess - Wikipedia

    Behind the ostium of the eustachian tube (ostium pharyngeum tuba auditiva) is a deep recess, the pharyngeal recess (fossa of Rosenmüller). Clinical significance [ edit ]

  7. Guttural pouch - Wikipedia

    en.wikipedia.org/wiki/Guttural_pouch

    The guttural pouches connect the middle ear to the pharynx. The opening into the pharynx is called the nasopharyngeal ostium, which is composed of the pharyngeal wall laterally and a fibrocartilaginous fold medially. This opening leads to a short soft tissue passageway into the respective guttural pouch.

  8. Tympanic cavity - Wikipedia

    en.wikipedia.org/wiki/Tympanic_cavity

    Its lateral edge corresponds with the remains of the petrosquamous suture. [1] The Atticus is the part of the tegmentum tympani where the stapes and incus are attached. The floor of the cavity (also called the jugular wall ) is narrow, and consists of a thin plate of bone (fundus tympani) which separates the tympanic cavity from the jugular fossa.

  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]
