Examples of adenoid in the following topics:
-
- The adenoids (pharyngeal tonsils) are a mass of lymphatic tissue found in the roof of the nasopharynx.
- The adenoids play a minor role in embyonic development and have a minor role in producing T-lymphocytes for the immune system after birth.
- While loss of the adenoids does not make a significant difference in immune system function, the procedure occasionally has complications.
- Above the adenoid, in the midline, is an irregular flask-shaped depression of the mucous membrane called the pharyngeal bursa.
- Compared to the adenoids of the nasopharynx, the palatine tonsils contain many folds (called crypts), and aren't ciliated like the adenoids are.
-
- It is performed in response to cases of repeated occurrence of acute tonsillitis or adenoiditis, obstructive sleep apnea, nasal airway obstruction, snoring, or peritonsillar abscess.
- For children, the adenoids are removed at the same time, a procedure called adenoidectomy.
- A mouth gag is used to prop the mouth open; if an adenoidectomy is also being performed, the adenoids are first removed with a curette; the nasopharynx is then packed with sterile gauze.
-
- For example, the adenoids and tubal tonsils are covered with the ciliated psuedostratified columnar epithelium of the nasopharynx, while the palatine and lingual tonsils are made up of the non-keratinized stratified squamous epithelium of the oropharynx.
- Chronic infection of the adenoids can cause adenoid hypertrophy, increases in cell size from repeated damage.
-
- The pharyngeal tonsils, more commonly referred to as the adenoids, are lymphoid tissue structures located in the posterior wall of the nasopharynx.
- It opens anteriorly, through the isthmus faucium, into the mouth, and contains the palatine tonsil—another grouping of adenoid tissue.
-
- It is found mainly in the lymph nodes, but also in the lymphoid follicles in tonsils, Peyer's patches, spleen, adenoids, skin, and other areas associated with the mucosa-associated lymphoid tissue (MALT).
-
- White pulp is secondary lymphoid tissue that is similar to that in the adenoid tonsils.
