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. [1] The artery passes superior-ward between the medial pterygoid muscle and ...
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.
The lesser palatine arteries give off tonsillary branches to supply the palatine tonsils. [3] They also gives off mucosal branches that usually supply the soft palate , [ 2 ] [ 4 ] and potentially the hard palate .
The ascending palatine artery is an artery is a branch of the facial artery which ascends along the neck before splitting into two terminal branches; one branch supplies the soft palate, and the other supplies the palatine tonsil and pharyngotympanic tube.
It descends through the greater palatine canal with the greater and lesser palatine branches of the pterygopalatine ganglion, and, emerging from the greater palatine foramen, runs forward in a groove on the medial side of the alveolar border of the hard palate to the incisive canal; the terminal branch of the artery passes upward through this canal to anastomose with the sphenopalatine artery.
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]
Tonsil stones may produce no symptoms or they may be associated with bad breath. [1] In fact, many dental professionals argue that tonsil stones are the leading cause of bad breath in their patients. The smell may be that of rotting eggs. [11] Tonsil stones tend to happen most often in people with longterm inflammation in their tonsils. [12]
