The oropharynx lies behind the oral cavity, extending from the uvula to the level of the hyoid bone. It opens anteriorly, through the isthmus faucium , into the mouth, while in its lateral wall, between the palatoglossal arch and the palatopharyngeal arch , is the palatine tonsil . [ 4 ]
The fauces is a part of the oropharynx directly behind the oral cavity as a subdivision, bounded superiorly by the soft palate, laterally by the palatoglossal and palatopharyngeal arches, and inferiorly by the tongue. The arches form the pillars of the fauces. The anterior pillar is the palatoglossal arch formed of the palatoglossus muscle.
When used unqualified, the term most commonly refers specifically to the palatine tonsils, which are two lymphoid organs situated at either side of the back of the human throat. The palatine tonsils and the adenoid tonsil are organs consisting of lymphoepithelial tissue located near the oropharynx and nasopharynx (parts of the throat).
Waldeyer's tonsillar ring (pharyngeal lymphoid ring, Waldeyer's lymphatic ring, or tonsillar ring) is a ringed arrangement of lymphoid organs in the pharynx.Waldeyer's ring surrounds the naso-and oropharynx, with some of its tonsillar tissue located above and some below the soft palate (and to the back of the mouth cavity).
In vertebrate anatomy, the throat is the front part of the neck, internally positioned in front of the vertebrae.It contains the pharynx and larynx.An important section of it is the epiglottis, separating the esophagus from the trachea (windpipe), preventing food and drinks being inhaled into the lungs.
Cancer of the oropharynx (very back of the throat) may start at the uvula. “This is rare, but can occur,” says Dr. Mehdizadeh. The primary cause is the human papillomavirus (HPV). Any part of ...
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.
Complete respiratory system. The respiratory tract is divided into the upper airways and lower airways.The upper airways or upper respiratory tract includes the nose and nasal passages, paranasal sinuses, the pharynx, and the portion of the larynx above the vocal folds (cords).
