Lingual tonsil

Lingual Tonsil

The Lingual tonsil is a part of the immune system located at the back of the tongue. It is a part of the Waldeyer's ring, which also includes the adenoids and the palatine tonsils. The lingual tonsil is composed of lymphatic tissue that functions in the immune response.

Anatomy

The lingual tonsil is located on the dorsal surface of the posterior third of the tongue. It is covered by stratified squamous epithelium and is densely packed with lymphocytes, a type of white blood cell that plays a key role in the immune response.

Function

The primary function of the lingual tonsil is to protect the body from infection. It does this by trapping and destroying pathogens that enter the body through the mouth or nose. The lingual tonsil also produces antibodies that help to fight off infections.

Clinical significance

In some cases, the lingual tonsil can become enlarged, a condition known as lingual tonsillitis. This can occur as a result of chronic irritation, such as from smoking or alcohol use, or from an infection. Symptoms of lingual tonsillitis can include a sore throat, difficulty swallowing, and a feeling of a lump in the throat.
