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.
The internal carotid and vertebral arteries. Right side. (Tonsillar labeled at center.) The tonsillar artery (or tonsillar branch of the facial artery) is (usually) a branch of the facial artery (though it sometimes arises from the ascending palatine artery instead) that represents the main source of arterial blood supply for the palatine tonsil.
The lingual tonsils are a collection of lymphatic tissue located in the lamina propria of the root of the tongue. [1] This lymphatic tissue consists of the lymphatic nodules rich in cells of the immune system (immunocytes). [2] The immunocytes initiate the immune response when the lingual tonsils get in contact with invading microorganisms ...
The adenoid 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 adenoid, unlike the palatine tonsils, has pseudostratified epithelium. [3] The adenoids are part of the so-called Waldeyer ring of lymphoid tissue which also includes the ...
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 ...
The tonsils also are lymphatic tissue and help mediate the ingestion of pathogens. Tonsils in humans include, from superior to inferior: nasopharyngeal tonsils (also known as adenoids), palatine tonsils, and lingual tonsils. Together this set of lymphatic tissue is called the tonsillar ring or Waldeyer's ring.
The throat contains various blood vessels, pharyngeal muscles, the nasopharyngeal tonsil, the tonsils, the palatine uvula, the trachea, the esophagus, and the vocal cords. [1] [2] Mammal throats consist of two bones, the hyoid bone and the clavicle. The "throat" is sometimes thought to be synonymous for the fauces. [3]
Tonsillitis is inflammation of the tonsils in the upper part of the throat. It can be acute or chronic. [8][9][2] Acute tonsillitis typically has a rapid onset. [10] Symptoms may include sore throat, fever, enlargement of the tonsils, trouble swallowing, and enlarged lymph nodes around the neck. [1][2] Complications include peritonsillar ...
