The adenoid, unlike the palatine tonsils, has pseudostratified epithelium. [3] The adenoids are part of the so-called Waldeyer ring of lymphoid tissue which also includes the palatine tonsils, the lingual tonsils and the tubal tonsils.
1 pharyngeal tonsil (or "adenoid"), located on the roof of the nasopharynx, under the sphenoid bone. 2 tubal tonsils on each side, where each auditory tube opens into the nasopharynx; 2 palatine tonsils (commonly called "the tonsils") located in the oropharynx; lingual tonsils, a collection of lymphatic tissue located on the back part of the tongue
The relationship between enuresis and obstructive apnea, and the benefit of adenoidectomy by implication, is complex and controversial. On one hand, the frequency of enuresis declines as children grow older. On the other, the size of the adenoid, and again by implication, any obstruction that they might be causing, also declines with increasing ...
A tonsillolith (also known as a "tonsil stone") is material that accumulates on the palatine tonsil. This can reach the size of a blueberry and is white or cream in color. The main substance is mostly calcium , but it has a strong unpleasant odor because of hydrogen sulfide and methyl mercaptan and other chemicals.
The adenoids, also known as the pharyngeal tonsils, are lymphoid tissue structures located in the posterior wall of the nasopharynx. Waldeyer's tonsillar ring is an annular arrangement of lymphoid tissue in both the nasopharynx and oropharynx. The nasopharynx is lined by respiratory epithelium that is pseudostratified, columnar, and ciliated.
Adenoid hypertrophy, also known as enlarged adenoids refers to an enlargement of the adenoid (pharyngeal tonsil) that is linked to nasopharyngeal mechanical blockage and/or chronic inflammation. [1] Adenoid hypertrophy is a characterized by hearing loss , recurrent otitis media , mucopurulent rhinorrhea , chronic mouth breathing , nasal airway ...
Also known as a pendectomy. Pericardiectomy is the partial or complete removal of the pericardial sac around the heart. Pharyngectomy is the removal of the pharynx (also called the throat). Pharyngolaryngoesophagectomy is the surgical removal of the pharynx, larynx and esophagus, usually as a result of cancer of the hypopharynx.
Lingual tonsils in humans also have long crypts but, unlike the crypts in the palatine tonsils, they're unbranched. [ 3 ] The small folds in adenoids are sometimes described as crypts.
