To change this template's initial visibility, the |state= parameter may be used: {{Tumors of lip, oral cavity and pharynx | state = collapsed}} will show the template collapsed, i.e. hidden apart from its title bar. {{Tumors of lip, oral cavity and pharynx | state = expanded}} will show the template expanded, i.e. fully visible.
The score is assessed by asking the patient, in a sitting posture, to open their mouth and to protrude the tongue as much as possible. [1] The anatomy of the oral cavity is visualized; specifically, the assessor notes whether the base of the uvula, faucial pillars (the arches in front of and behind the tonsils) and soft palate are visible.
In birds, it consists of the trachea, the syrinx, the oral cavity, the upper part of the esophagus, and the beak. In mammals, it consists of the laryngeal cavity, the pharynx, the oral cavity, and the nasal cavity. [1] The estimated average length of the vocal tract in men is 16.9 cm and 14.1 cm in women. [2]
The body cavity immediately behind the mouth opening, known as the oral cavity (or cavum oris in Latin), [2] is also the first part of the alimentary canal, which leads to the pharynx and the gullet. In tetrapod vertebrates , the mouth is bounded on the outside by the lips and cheeks — thus the oral cavity is also known as the buccal cavity ...
The mouth consists of two regions: the vestibule and the oral cavity proper. The vestibule is the area between the teeth, lips and cheeks. [3] The oral cavity is bounded at the sides and in front by the alveolar process (containing the teeth) and at the back by the isthmus of the fauces. Its roof is formed by the hard palate.
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.

The tongue is attached to the floor of the oral cavity by the frenulum. Sketch of an open mouth showing the frenulum and surrounding structures. Superficial veins run through the base of the frenulum known as varicosities. Their presence is normal, becoming more and more prominent as one ages. [5]
