What is the structure of the pharyngeal tonsils?
Pharyngeal tonsils/adenoids These are the most superior tonsils that lie in the superior part of the nasopharynx. It is attached to the periosteum of the sphenoid bone by connective tissue.

How tonsils are formed?
Your tonsils are made up of crevices, tunnels, and pits called tonsil crypts. Different types of debris, such as dead cells, mucus, saliva, and food, can get trapped in these pockets and build up. Bacteria and fungi feed on this buildup and cause a distinct odor. Over time, the debris hardens into a tonsil stone.
Are pharyngeal tonsils paired?

Where is the pharyngeal tonsil located and what is its function quizlet?
A pharyngeal tonsil is found in the posterior wall of the NASOPHARYNX. When the pharyngeal tonsil becomes enlarged, it is called ADENIODS. Lingual tonsils are located along the posterior one-third of the TONGUE. Within the tonsils are LYMPHATIC NODULES that help protect against foreign substances.

Where are the palatine and pharyngeal tonsils located?
The palatine tonsils and the adenoid tonsil are organs consisting of lymphoepithelial tissue located near the oropharynx and nasopharynx (parts of the throat).
What is the pharyngeal tonsil?
The pharyngeal tonsil refers to a collection of lymphoid tissue within the mucosa of the roof of the nasopharynx. When enlarged, the pharyngeal tonsil is also known as the adenoids. It is located in the midline of the nasopharynx, and forms the superior aspect of Waldeyer’s ring.
What is the structure of the tonsils?
The tonsils are collections of lymphatic tissue located within the pharynx. They collectively form a ringed arrangement, known as Waldeyer’s ring: The tonsils are classified as mucosa-associated lymphoid tissue (MALT), and therefore contain T cells, B cells and macrophages.
What is Waldeyer’s ring of tonsils?
The Tonsils (Waldeyer’s Ring) 1 Lingual Tonsil. The lingual tonsil refers to numerous lymphoid nodules located within the submucosa of the posterior third of the tongue. 2 Pharyngeal Tonsil. The pharyngeal tonsil refers to a collection of lymphoid tissue within the mucosa of the roof of the nasopharynx. 3 Tubal Tonsils. 4 Palatine Tonsils.
What is the epithelial covering of the tubal tonsils?
The epithelial covering of the tubal tonsils is ciliated pseudostratified epithelium. The neurovascular supply is similar to other structures in the nasopharynx. Arterial supply is chiefly via the ascending pharyngeal artery and venous drainage is to the pharyngeal plexus. Innervation is via the maxillary and glossopharyngeal nerves.
