Waldeyer’s Tonsillar Ring

Description

Tissues coming in contact with the external world are always rich in lymphoid tissues, containing immune cells that guard them against pathogens.

The mouth and nose are no exception; they contain masses of lymphatic tissue known as tonsils, which are collectively known as Waldeyer’s tonsillar ring .

Waldeyer’s tonsillar ring

This ring consists of two paired (one on each side), and two unpaired tonsils:

Tonsil Type Location
Pharyngeal Unpaired The roof of the nasopharynx
Tubal Paired Around the auditory tube
Palatine Paired Between the two glossal arches, at the isthmus of the fauces
Lingual Unpaired Located at the back of the base of the tongue
Tonsils (tubal tonsils are not shown) (Credit: OpenStax, CC BY 4.0)
