What is the difference between palatine tonsil and lingual tonsil?

What is the difference between palatine tonsil and lingual tonsil?

The palatine tonsils are the ones that are located near the opening of the oral cavity into the pharynx. Lingual tonsils are located on the posterior surface of the tongue, which also places them near the opening of the oral cavity into the pharynx.

What does lingual tonsillitis look like?

Lingual tonsils are usually associated with the foliate papillae and are recognized as bilateral red, glistening papules and nodules on the posterolateral border of the tongue (Fig. 9.19).

Can you see your lingual tonsils?

Your lingual tonsils are visible to the naked eye as bunches of lymphatic tissue on the sides of your tongue at its base.

What causes enlarged lingual tonsils?

The most common cause of lingual tonsillar enlargement is compensatory enlargement following tonsillectomy. Other potential causes include lymphoma, chronic infection and HIV. Irritation such as from smoking and gastro‐oesophageal reflux disease (GORD) can also cause lingual tonsil hypertrophy.

What does the palatine tonsil look like?

Palatine tonsils, commonly called the tonsils and occasionally called the faucial tonsils, are tonsils located on the left and right sides at the back of the throat, which can often be seen as flesh-colored, pinkish lumps.

What is the function of the Palatine and lingual tonsils?

The palatine tonsils sit in the back of the throat and are made up of lymphatic tissue. Along with the pharyngeal, tubal, and the lingual tonsils, they act as a defence against possible infections. The palatine tonsils are oval-shaped lymphatic tissue located at both sides of the back of the throat.

What are lingual tonsils?

The lingual tonsils are a collection of lymphatic tissue located in the lamina propria of the root of the tongue. This lymphatic tissue consists of the lymphatic nodules rich in cells of the immune system (immunocytes).

What is palatine tonsil?

The palatine (or faucial) tonsils, commonly referred to as tonsils, are bundles of lymphatic tissue located in the lateral oropharynx. They sit in the isthmus of the fauces, bordered anteriorly by the palatoglossal arch and posteriorly by the palatopharyngeal arch.

What do palatine tonsils look like?

What is behind palatine tonsils?

The tonsils (palatine tonsils) are a pair of soft tissue masses located at the rear of the throat (pharynx). Each tonsil is composed of tissue similar to lymph nodes, covered by pink mucosa (like on the adjacent mouth lining). Running through the mucosa of each tonsil are pits, called crypts.

What are the palatine tonsils?

The palatine tonsils are commonly referred to as ‘ the tonsils ‘. They are located within the tonsillar bed of the lateral oropharynx wall – between the palatoglossal arch (anteriorly) and palatopharyngeal arch (posteriorly). They form the lateral part of the Waldeyer’s ring. Each tonsil has free medial surface which projects into the pharynx.

Why are palatine tonsils pink in color?

  The palatine tonsils also serve as a component of Waldeyer’s ring which in addition to the palatine tonsils consists of the adenoids, tubal tonsil, and lingual tonsil.[1] Typically, when inflammation and infection are absent, these structures have a pink color.

What is the lingual tonsil?

The lingual tonsil refers to numerous lymphoid nodules located within the submucosa of the posterior third of the tongue. This tonsil is responsible for the irregular appearance of the posterior tongue surface. and forms the inferior part 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.
