EL ANILLO DE WALDEYER PDF

Waldeyer's tonsillar ring pharyngeal lymphoid ring , Waldeyer's lymphatic ring , or tonsillar ring is a ringed arrangement of lymphoid organs in the pharynx. Waldeyer's ring surrounds the naso- and oropharynx , with some of its tonsillar tissue located above and some below the soft palate and to the back of the mouth cavity. These authors simply look at the left and right halves of the pharyngeal tonsil as two tonsils. Many authors also speak of lingual tonsils in the plural , because this accumulation of lymphoid tissue consists of a number of little prominences — many smaller rounded masses.
