Document Summary

First entry point of food and drink coming into body. Oral cavity is where food is ingested and prepared for digestion. Chemical: enzymes released in saliva that breaks down food. Oral vestibule: space between teeth and lips. On upper and lower parts of mouth. Space above tongue, between upper and lower dental arches. At rest, the tongue would be fully occupying this region. Hard palate: part of maxillary bone and palatine bones. Soft palate: a smooth connective tissue at posterior side of oral cavity. Not orbicularis oris, which is the muscle that helps moves lips. Used for grasping food, clearing food into oral cavity. Lips and cheeks are important for articulation and forming speech. Labial frenulum: connective point of lips to gingivae (gums). They are mucosal folds that will hold lip to oral vestibule. Mucosal membrane on inner lining of oral cavity. Buccal fat pad in babies cheeks is more prominent because they don"t have well developed buccinator muscles.
