Palatine tonsils consist of approximately 15 crypts, which result in a large internal surface. The tonsils contain four lymphoid compartments that influence immune functions, namely the reticular crypt epithelium, the extrafollicular area, the mantle zones of lymphoid follicles, and the follicular germinal centers. In human palatine tonsils ...
The human palatine tonsils (PT) are covered by stratified squamous epithelium that extends into deep and partly branched tonsillar crypts, of which there are about 10 to 30. [1] The crypts greatly increase the contact surface between environmental influences and lymphoid tissue.
Tonsil stones, also known as tonsilloliths, are mineralizations of debris within the crevices of the tonsils. [1][3] When not mineralized, the presence of debris is known as chronic caseous tonsillitis (CCT). [1] Symptoms may include bad breath, [1] foreign body sensation, sore throat, pain or discomfort with swallowing, and cough. [4]
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 ...
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.
D014068. MedlinePlus. 003013. [edit on Wikidata] Tonsillectomy is a surgical procedure in which both palatine tonsils are fully removed from the back of the throat. [1] The procedure is mainly performed for recurrent tonsillitis, throat infections and obstructive sleep apnea (OSA). [1]
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 ...
The tonsillar fossa (or tonsillar sinus) is a space delineated by the triangular fold (plica triangularis) of the palatoglossal and palatopharyngeal arches within the lateral wall of the oral cavity. [1] In many cases, however, this sinus is obliterated by its walls becoming adherent to the palatine tonsils.
