Which bones compose the oral cavity?
The basic bony framework of the oral cavity is formed by three main bones; the mandible or the lower Jaw bone, the maxilla or the upper jaw bone, and the palatine bones.
What are the two parts of the oral cavity What are the boundaries of each part?
The oral cavity lies anterior to the oropharynx and is separated from it by the circumvallate papillae; soft palate; and anterior tonsillar pillars, which make up its posterior boundary. The oral cavity is bounded superiorly by the hard palate, laterally by the cheek, and inferiorly by the mylohyoid muscle.
What are the boundaries of oral cavity?
The oral cavity is bounded anteriorly by the lips, laterally by the cheeks, superiorly by the hard palate, and inferiorly by the mucosa covering the superior surface of the tongue and the sheet of muscles attaching to the inner side of the mandible, including geniohyoid, mylohyoid, and digastric.
What structure demarcates the border between the oral and oropharyngeal cavity?
Soft Palate It is continuous laterally with the tonsillar pillars and attaches anteriorly to the hard palate. It forms both the roof of the oropharynx and the floor of the nasopharynx. The soft palate demarcates the oral cavity from the oropharynx as well as the oropharynx from the nasopharynx.
What is the difference between the vestibule and the oral 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. 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.
Is the tongue part of the oral cavity?
Refers to the mouth. It includes the lips, the lining inside the cheeks and lips, the front two thirds of the tongue, the upper and lower gums, the floor of the mouth under the tongue, the bony roof of the mouth, and the small area behind the wisdom teeth.

Which structure acts as the valve closing and opening the space between the oral and nasal cavities?
The palate separates the oral and nasal cavities; the posterior part, the velum or soft palate, contains muscle and glands that together with the lateral and posterior pharyngeal walls, form the anatomical velopharyngeal sphincter, closing off the nasal cavity from the oropharynx during swallowing, blowing, sucking.
