Tonsils

Tonsils

 

       These are the largest lymph nodules. They provide protection against bacteria and other harmful materials. In adults the tonsils decrease in size and may disappear. There are 3 groups of tonsils in the pharyngeal walls. Of the three, the palatine tonsils are usually refered to as “the tonsils”. These are larger lymphoid masses on each side of the junction between the oral cavity and the pharynx. The pharyngeal tonsil or adenoid are found near the junction between the nasal cavity and the pharynx. The lingual tonsil is a loosely associated collection of lymph nodules on the posterior surface of the tongue.
