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.
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.

2. Strep throat is lurking. Though it’s not as common in adults, strep throat is a bacterial infection that can cause swollen tonsils and inflammation, says Dr. Zalvan.
Lingual tonsils are covered externally by stratified squamous epithelium (nonkeratinized) that invaginates inward forming tonsillar crypts. Beneath the epithelium is a layer of lymphoid nodules containing lymphocytes. Mucous glands located at the root of the tongue are drained through several ducts into the crypts of the lingual tonsils.
The tubal tonsil may also be known as the Gerlach tonsil. [3] It is very close to the torus tubarius, [4] which is why this tonsil is sometimes also called the tonsil of (the) torus tubarius. [5] Equating the torus with its tonsil however might be seen as incorrect or imprecise.
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 .
The cerebellar tonsil (Latin: tonsilla cerebelli) is a paired 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 of which is not to be confused with the ...
