Waldeyer's Ring

Waldeyer's Ring is an aggregation of lymphoid tissue seen in the subepithelial lining of pharynx guarding the nasopharynx and oropharynx in the form of a ring.

The ring is bounded by-

1. Palatine Tonsils ( also called as Faucial Tonsil)- Situated in between the anterior and posterior pillars on each side of oropharynx
2. Adenoids (aka Lushka's Tonsil)- Lies at the junction of roof and posterior wall of nasopharynx
3. Tubal Tonsils ( aka Gerlach's Tonsil)- Lies in the fossa of rosenmuller behind the eustatian tube opening
4. Lateral Pharyngeal Band and Nodules

Hope that helped!
