Tonsillar crypts. Low-power microscope magnification of a cross-section through one of the tonsillar crypts (running diagonally) as it opens onto the surface of the throat (at the top). Stratified epithelium (e) covers the throat's surface and continues as a lining of the crypt. Beneath the surface are numerous nodules (f) of lymphoid tissue.
The palatine tonsils with the soft palate, uvula, and tongue visible. Palatine tonsils, commonly called the tonsils and occasionally called the faucial tonsils, [2] 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. Tonsils only present as "white lumps" if they are ...
Tonsil stones, also known as tonsilloliths, are mineralizations of debris within the crevices of the tonsils. [1][3] When not mineralized, the presence of debris is known as chronic caseous tonsillitis (CCT). [1] Symptoms may include bad breath, [1] foreign body sensation, sore throat, pain or discomfort with swallowing, and cough. [4]
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. When used unqualified, the term most ...
Lingual tonsils are covered externally by stratified squamous epithelium (nonkeratinized) that invaginates inward forming tonsillar crypts. Beneath the epithelium is a layer of lymphoid nodules containing lymphocytes. Mucous glands located at the root of the tongue are drained through several ducts into the crypts of the lingual tonsils.
Crypt (anatomy) Crypts are anatomical structures that are narrow but deep invaginations into a larger structure. One common type of anatomical crypt is the Crypts of Lieberkühn. [1] However, it is not the only type: some types of tonsils also have crypts. Because these crypts allow external access to the deep portions of the tonsils, these ...
The tonsil is the most common site of squamous cell carcinoma in the oropharynx. It comprises 23.1% of all malignancies of the oropharynx. [1] The tumors frequently present at advanced stages, and around 70% of patients present with metastasis to the cervical lymph nodes. [2] . The most reported complaints include sore throat, otalgia or dysphagia.
Structure. Each tubal tonsil is located posterior to the opening of the Eustachian tube on the lateral wall of the nasopharynx. [1] It is one of the four main tonsil groups forming Waldeyer's tonsillar ring. [2] This ring also includes the palatine tonsils, the lingual tonsils, and the adenoid. [2]
