The adenoid is a mass of lymphoid tissue located behind the nasal cavity, in the roof and the posterior wall of the nasopharynx, [ 1] where the nose blends into the throat. 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 ...
Otorhinolaryngology. 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.

Tonsil. The tonsils are a set of lymphoid organs facing into the aerodigestive tract, which is known as Waldeyer's tonsillar ring and consists of the adenoid tonsil (or pharyngeal tonsil), two tubal tonsils, two palatine tonsils, and the lingual tonsils. These organs play an important role in the immune system.

Tonsillectomy is mainly undertaken for sleep apnea and recurrent or chronic tonsillitis. [ 1] It is also carried out for peritonsillar abscess, periodic fever, aphthous stomatitis, pharyngitis and adenitis (PFAPA), guttate psoriasis, nasal airway obstruction, tonsil cancer and diphtheria carrier state. For children, tonsillectomy is usually ...
Pharyngeal arch. The pharyngeal arches, also known as visceral arches, are structures seen in the embryonic development of vertebrates that are recognisable precursors for many structures. In fish, the arches are known as the branchial arches, or gill arches. In the human embryo, the arches are first seen during the fourth week of development.
