Document Summary

Oral vestibule: space btw cheeks/lips + teeth/gums; oral cavity: lies btw teeth and gums; labial frenulum: median fold joins lip to gum: palate: roof of mouth; 2 parts: hard palate anteriorly & soft palate posteriorly. Hard plate: underlain by palatine bones & palatine process of maxillae; forms rigid surface against tongue; raphe mucosa: slightly corrugated (helps friction). Soft plate: mostly skeletal muscle; close nasopharynx during swallow; anchored to tongue by palatoglossal arches & oropharynx wall by palatopharyngeal arches; form fauces (oropharynx arched area with palatine tonsils); uvula: downward from free edge of soft palate. Intrinsic: on tongue, not attached to bone, allow shape change; extrinsic: attach skull bone or soft palate to tongue; change tongue position. Median septum divides tongue; lingual frenulum: mucosa folds; attaches tongue to mouth floor; limit posterior movement. Foliate papillae: pleat-like; on lateral of posterior tongue; infancy/childhood.
