The palatine tonsils are located in the isthmus of the fauces, between the palatoglossal arch and the palatopharyngeal arch of the soft palate.. The palatine tonsil is one of the mucosa-associated lymphoid tissues (MALT), located at the entrance to the upper respiratory and gastrointestinal tracts to protect the body from the entry of exogenous material through mucosal sites.
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 ...
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 skeletal section of the head and neck forms the top part of the axial skeleton and is made up of the skull, hyoid bone, auditory ossicles, and cervical spine. The skull can be further subdivided into: the facial bones (14 bones: 2-zygomatic, 2-maxillary, 2-palatine, 2-nasal, 2-lacrimal, vomer, 2-inferior conchae, mandible).
Fauces (throat) A view of the fauces through the mouth cavity. The cheeks have been slit transversely and the tongue pulled forward. (Fauces labelled as Isthmus faucium at center right.) The fauces, isthmus of fauces, or the oropharyngeal isthmus is the opening at the back of the mouth into the throat. [1] It is a narrow passage between the ...
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 palatine bones are situated at the back of the nasal cavity between the maxilla and the pterygoid process of the sphenoid bone. They contribute to the walls of three cavities: the floor and lateral walls of the nasal cavity, the roof of the mouth, and the floor of the orbits. They help to form the pterygopalatine and pterygoid fossae, and ...
Palatoglossal arch. The mouth cavity. The cheeks have been slit transversely and the tongue pulled forward. (Glossopalatine arch labeled at upper right.) The palatoglossal arch (glossopalatine arch, anterior pillar of fauces) on either side runs downward, lateral (to the side), and forward to the side of the base of the tongue, and is formed by ...
