Tonsil

Tonsils or tonsils are lymphoid organs in the area of oral cavity and pharynx. They form the lymphatic pharyngeal ring in its entirety. When one speaks of almonds, one usually means the tonsils ( palatine tonsil ), which lie at the back end of the palate between the two palatal arch ( arcus palatoglossus and palatopharyngeal arch ).

Tonsils are the first stop of the body, are localized to the bacteria, and thus function as a detector of harmful organisms.

Construction

Almonds are demarcated by connective tissue collections of lymph nodules ( follicles ) directly under the epithelium of the mucosa. To increase the surface the almond can Schleimhautwulst out a bulge ( Beetmandel ), almonds without relief formation on the mucous membrane is called plate almonds. Often lymphoreticular tissues ( tonsillar Fossulae ) around pits and these recessed into the ( palate ) almond Epitheltaschen, called crypts ( crypts tonsillae ) arranged ( pit almond ), such that the almonds have a rugged surface relief. Mostly almonds are underlain by Spüldrüsen.

Diseases

Because of the direct food contact and the rugged surface are particularly inflammation of the tonsils quite frequently (tonsillitis ). They cause a sore throat and fever. In certain cases it may be necessary removal ( tonsillectomy ).

Proliferations ( hyperplasia ) can affect all tonsils. In the pharyngeal tonsil, they are called adenoids ( " polyps " ) and are usually surgically removed ( adenoidectomy ).
