Waldeyer's tonsillar ring
From Wikipedia, the free encyclopedia
Waldeyer's tonsillar ring is an anatomical term describing the lymphoid tissue ring located in the nasopharynx.
It was named after the nineteenth centuary German anatomist Heinrich Wilhelm Gottfried von Waldeyer-Hartz.[1]
The ring consists of (from superior to inferior):
- Adenoids (also termed pharyngeal tonsils)
- Tubal tonsils
- Palatine tonsils (more commonly termed "the tonsils")
- Lingual tonsils
