The tonsils are a set of lymphoid organs facing into the aerodigestive tract, which is known as Waldeyer's tonsillar ring and consists of the adenoid tonsil (or pharyngeal tonsil), two tubal tonsils, two palatine tonsils, and the lingual tonsils. These organs play an important role in the immune system. When used unqualified, the term most ...

Anatomical terms of neuroanatomy. [edit on Wikidata] The cerebellar tonsil (Latin: tonsilla cerebelli) is a rounded lobule on the undersurface of each cerebellar hemisphere, continuous medially with the uvula of the cerebellar vermis and superiorly by the flocculonodular lobe. Synonyms include: tonsilla cerebelli, amygdala cerebelli, the latter ...
The palatine tonsils are located in the isthmus of the fauces, between the palatoglossal arch and the palatopharyngeal arch of the soft palate.. The palatine tonsil is one of the mucosa-associated lymphoid tissues (MALT), located at the entrance to the upper respiratory and gastrointestinal tracts to protect the body from the entry of exogenous material through mucosal sites.
Tonsillar crypts. Low-power microscope magnification of a cross-section through one of the tonsillar crypts (running diagonally) as it opens onto the surface of the throat (at the top). Stratified epithelium (e) covers the throat's surface and continues as a lining of the crypt. Beneath the surface are numerous nodules (f) of lymphoid tissue.
In anatomy, the pharyngeal tonsil, also known as the nasopharyngeal tonsil or adenoid, is the superior-most of the tonsils. It is a mass of lymphoid tissue located behind the nasal cavity , in the roof and the posterior wall of the nasopharynx , [ 1 ] where the nose blends into the throat .
Anatomical terminology. [edit on Wikidata] The torus tubarius (or torus of the auditory tube) is an elevation of the mucous membrane of the nasal part of the pharynx formed by the underlying base of the cartilaginous portion of the Eustachian tube (auditory tube). The torus tubarius is situated behind the pharyngeal orifice of the auditory tube.
Fauces (throat) A view of the fauces through the mouth cavity. The cheeks have been slit transversely and the tongue pulled forward. (Fauces labelled as Isthmus faucium at center right.) The fauces, isthmus of fauces, or the oropharyngeal isthmus is the opening at the back of the mouth into the throat. [1] It is a narrow passage between the ...
