Lingual tonsil

Synonyms: Tonsil of Luschka, Adenoid , The tonsils are a collection of lymphoid tissue that are found in the mucosa of the pharynx. These masses of lymphoid tissue form an important part of our immune system and act as the first line of defense against ingested or inhaled pathogens. There are four primary groups of tonsils which are arranged into a ring around the This article will look at the Key facts about the tonsils Definition Collection of lymphoid tissue clustered in the mucosa of the pharynx. Function of the tonsils Provide immunological protection; first line defense against ingested or inhaled pathogens Types of tonsils and locations - Pharyngeal tonsils/adenoids: single tonsil located in the roof of the nasopharynx - Tubal tonsils: bilateral tonsils located inside the mucosa of the lateral walls of the nasopharynx - Palatine tonsils: bilateral tonsils located on either side of the oropharynx and lie between the palatopharyngeal and palatoglossal arches and posterior to the oropharyngeal isthmus - Lingual tonsils: single tonsil located at the base of the posterior â…“ of the tongue + Show all Anatomy The tonsils are a type of mucosa associated lymphoid tissue (MALT) which surround the opening of the nasal and oral cavities. They contain aggregations of lymphoid nodules that are spread through the mucosal lining of the pharynx. These aggregations contain T cells, B cells and macrophages which are key for immunological protection against any pathogens entering the ...

The palatine or faucial tonsils, commonly known as just tonsils, sit in the back of the throat and consist of lymphatic tissue. Along with the pharyngeal, tubal, and lingual tonsils, they defend against possible infections. The palatine tonsils are oval-shaped lymphatic tissue located at both sides of the back of the throat. People can see their palatine tonsils by opening their mouths and looking in the mirror. When a person refers to tonsils, they usually refer to the palatine tonsils. While they protect the body, complications such as infection and swelling can cause health problems. Read on for conditions associated with the tonsils, symptoms, diagnostic tests, and treatments. The palatine tonsils play an important role in trapping bacteria and viruses as they enter the body. However, this can make them prone to infection. Doctors refer to an infection in the tonsils as When there is a bacterial infection in the tonsils, group A Streptococcus is usually the cause. Doctors refer to these infections as • a sore throat • difficulty swallowing • a high temperature • coughing • a headache or earache • nausea • fatigue • When the palatine tonsils become enlarged, it is called tonsil hypertrophy. This type of condition is particularly However, the swollen tissue caused by large tonsils and adenoids can begin to partially obstruct the throat and cause breathing problems. These symptoms are the most common cause of In adults, the cause of sleep apnea can result from the followi...

Viral and bacterial infections, such as tonsilitis and strep throat, can cause swollen tonsils. Many infections go away on their own, but severe bacterial infections may need antibiotic treatment. In this article, we discuss the common causes and treatment of swollen tonsils. We also explain when to see a doctor. Some viral and bacterial infections can cause swollen tonsils. They include: Acute tonsilitis Viruses and bacteria People can take Over-the-counter (OTC) medications, such as acetaminophen or Strep throat Streptococcus pyogenes Doctors treat severe cases of Viruses can also cause strep throat with slightly different accompanying symptoms, including a cough, runny nose, and mouth ulcers. Adenoviruses The Adenoviruses may also cause recurrent tonsil infections in people with a weakened immune system, though these infections may not always present with symptoms. As most adenoviruses are mild, people do not usually need treatment, and the virus may go away on its own. Epstein-Barr virus The symptoms of an Epstein-Barr virus infection, such as mononucleosis, include swollen tonsils, fever, fatigue, and skin rashes. Adults and teenagers usually recover in There is no vaccine against the Epstein-Barr virus. However, as the virus can spread through the exchange of bodily fluids, especially saliva, people can often avoid it by maintaining a distance from people who have the virus and not sharing toothbrushes and drinks with them. Once a person has the virus, it will remain...

Overview Tongue cancer is a form of cancer that begins in the cells of the tongue. Several types of cancer can affect the tongue, but tongue cancer most often begins in the thin, flat squamous cells that line the surface of the tongue. The type of cells involved in your tongue cancer helps determine your prognosis and treatment. Where your tongue cancer occurs also affects your treatment. Tongue cancer can occur: • In the mouth, where it may be more likely to be seen and felt (oral tongue cancer). This type of tongue cancer tends to be diagnosed when the cancer is small and more easily removed through surgery. • In the throat, at the base of the tongue, where tongue cancer may develop with few signs and symptoms (hypopharyngeal tongue cancer). Cancer at the base of the tongue is usually diagnosed at an advanced stage, when the tumor is larger and the cancer has spread into the lymph nodes in the neck. Increasingly, cancers at the base of the tongue are associated with human papillomavirus (HPV), which has a profound effect on the prognosis and treatment of the cancer. Treatment for tongue cancer typically involves surgery to remove the cancer. Chemotherapy, radiation therapy and targeted drug therapy also may be recommended. Treatment for advanced tongue cancers can impact your ability to speak and eat. Working with a skilled rehabilitation team can help you cope with changes that result from tongue cancer treatment. • AskMayoExpert. Head and neck cancers. Rochester, Minn....

No single theory of pathogenesis has yet been accepted, however. Viral infection with secondary bacterial invasion may be one mechanism of the initiation of chronic disease, In children, t...

A tonsillectomy is a surgical procedure that removes the tonsils. The tonsils can often become infected. In fact, tonsillitis is a fairly common illness among children. The tonsils are glands that fight infections with white blood cells, though they are prone to developing infections themselves. The tonsils sit at the back of your throat, and issues such as swallowing, sore throat, and bad breath can often be reasons to remove them. This article explains what a tonsillectomy is, why a person might have one, and what to expect during the recovery process. If you need a tonsillectomy, knowing what recovery is like and preparing for it can help make the process smoother. The adenoids are located behind the nose at the roof of the mouth, and the tonsils are located on either side of the throat. Both of these glands fight infections and help the An illness called tonsillitis, which occurs can affect these glands. Bacterial and viral infections can lead to Trusted Source PubMed Central Highly respected database from the National Institutes of Health • a sore throat • • a fever • a • nausea • • bad breath However, more severe symptoms include: • white, • painful, swollen glands in the neck that feel like • difficulty breathing Tonsillitis usually lasts less than a week, but you should seek medical advice if the symptoms continue to linger. If you or your child repeatedly gets tonsillitis, or if the symptoms of a bacterial infection do not get better with antibiotics, evaluation f...

Tonsils are part of the immune system and contain an abundance of white blood cells to combat germs from entering the body. They are part of mucous-associated lymphoid tissue (MALT). 1 Tonsils are made with lymphocytes and cells that prevent and fight infections. 1 The tonsils have antigen-presenting cells on their surface that communicate with the B and T cells as part of the immune system. The B cells produce antibodies IgA to provide immune protection on mucosal surfaces. The T cells directly kill the invaders by engulfing them or indirectly by stimulating other cells of the immune system. Tonsils are covered with pink mucosa with crypts, which are small pits in each tonsil. Crypts embedded in them are normal anatomy. The average adult has 10 to 20 crypts. They are generally small and debris-free, although they may collect food, mucus, and debris. When this happens, it can lead to bad breath, a feeling of something stuck in the throat, a chronic sore throat, foul-smelling cheese-like clumps in the mouth, or tonsil stones. 2 Waldeyer’s ring consists of four tonsils (see Figure 1). They form a ring around the opening of the throat, mouth, and nose. This positioning prevents germs, bacteria, and viruses from entering the body via mouth or nose. The four types of tonsils are adenoids, lingual, palatine, and tubal. 3 Figure 1 Courtesy of Nicholas Polys Adenoids (pharyngeal tonsil of tonsillar pharyngealis) − The adenoids are found high in the throat behind the nose and can o...
