Document Summary
Oral cavity: includes mouth, teeth, gums, tongue, palate, and palatine tonsils. Oral vestibule: the space between teeth and lips. Oral cavity proper: the space between top and bottom teeth where tongue occupies at rest. Upper and lower lips are muscular folds surrounding mouth (covered externally by skin, and internally by mucous membrane) Meant for grasping food, clearing food, sucking, speech, and osculation (kissing) Labial frenula= muscular folds in midline of lip. (think lip friend- in middle) Buccal fat pouches are more prominent in babies. It reinforces cheeks and prevents collapse while sucking. Gingivae proper is firmly attached to alveolar processes and teeth. Excellent blood supply and nervous innervation- which is why gingivitis can spread to other structures. Hard conical structures set within alveoli of upper and lower jaws. Used in mastication and assist in articulation (tongue and teeth) 3 molars, 2 premolars, 2 incisors (lateral and medial) and 1 canine = 32 teeth.
