The Oral Cavity - Randwick College Wiki
Stage 1 Anatomy & Physiology of the Head & Neck Class Exercise 1 Class Exercise The Oral Cavity 2 Class Exercise The Oral Cavity Topics 1. Functions 2. Areas 3. Important landmarks 3 Class Exercise The Oral Cavity The function of the oral cavity is: 1. Analysis of material before swallowing 2. Mechanical processing through the actions of the teeth, tongue, and palatal surfaces 3. Lubrication by mixing with mucus and salivary gland secretion 4. limited digestion of carbohydrates and lipids 4 Class Exercise The Oral Cavity The oral cavity is lined with mucous membrane tissue 5 Class Exercise The Oral Cavity The oral cavity consists of two areas: The vestibule is the space between the teeth and the inner mucosal lining of the lips and cheeks. The oral cavity proper is the space contained within the upper and lower dental arches. 6 Maxillary Vestibule Mandibular Vestibule 7 Class Exercise The Oral Cavity The zone adjacent to the vestibule is the Alveolar Mucosa and is the dark pink area 8 Alveolar Mucosa Maxillary Vestibule Mandibular Vestibule 9 Class Exercise The Oral Cavity As you can see here, the Gingiva is a lighter pink 10 Class Exercise The Oral Cavity The alveolar mucosa and gingiva are separated from each other by a sharp scalloped line, the Mucogingival Junction MGJ 11 Mucogingival Junction Alveolar Mucosa Maxillary Vestibule Mandibular Vestibule 12 Class Exercise The Oral Cavity The gingiva is subdivided into Attached Gingiva (A) and Free Gingiva (F) Gingival Sulcus A A 13 Mucogingival Junction Alveolar Mucosa Free Gingiva Maxillary Vestibule Attached Gingival Mandibular Vestibule 14 Class Exercise The Oral Cavity Maxillary Labial Frenum Mandibular Labial Frenum 15 Mucogingival Junction Alveolar Mucosa Maxillary Labial Frenum Free Gingiva Maxillary Vestibule Attached Gingival Mandibular Labial Frenum Mandibular Vestibule 16 Mucogingival Junction Alveolar Mucosa Maxillary Labial Frenum Free Gingiva Maxillary Vestibule Attached Gingival Mandibular Buccal Frenum Mandibular Labial Frenum Mandibular Vestibule 17 Class Exercise The Oral Cavity Proper 18 Class Exercise The Oral Cavity Proper The roof of the oral cavity proper is formed by the Hard Palate 19 Hard Palate Class Exercise 20 Class Exercise The Oral Cavity Proper Incisive Papilla 21 Incisive Papilla Hard Palate Class Exercise 22 The Oral Cavity Proper The Palatine Raphe is more prominent in some people than in others Class Exercise 23 Incisive Papilla Hard Palate Class Exercise Palatine Raphe 24 The Oral Cavity Proper Radiating from the incisive papilla and anterior portions of the palatine raphe are irregular branching ridges termed the Palatine Rugae Class Exercise 25 Incisive Papilla Hard Palate Class Exercise Palatine Rugae Palatine Raphe 26 The Oral Cavity Proper The Fovea Palatinae Class Exercise 27 Incisive Papilla Hard Palate Palatine Rugae Palatine Raphe Palatine Fovea Class Exercise 28 The Oral Cavity Proper The broken line outlines this patient's Soft Palate Class Exercise 29 Incisive Papilla Hard Palate Palatine Rugae Palatine Raphe Soft Palate Palatine Fovea Class Exercise 30 The Oral Cavity Proper The Tuberosity is an important landmark in prosthodontics Class Exercise 31 Incisive Papilla Hard Palate Palatine Rugae Palatine Raphe Tuberosity Soft Palate Palatine Fovea Class Exercise 32 The Oral Cavity Proper The Hamular Notch Class Exercise 33 Incisive Papilla Hard Palate Palatine Rugae Palatine Raphe Tuberosity Soft Palate Hamular Notch Palatine Fovea Class Exercise 34 The Oral Cavity Proper The Retromolar Pad is another important landmark in prosthodontics Class Exercise 35 The Oral Cavity Proper The Uvula Class Exercise 36 Incisive Papilla Hard Palate Palatine Rugae Palatine Raphe Tuberosity Soft Palate Hamular Notch Uvula Palatine Fovea Class Exercise 37 The Oral Cavity Proper Alveolar Process with teeth Class Exercise 38 The Oral Cavity Proper Alveolor Process without teeth Class Exercise 39 The Oral Cavity Proper The Floor of the Mouth Class Exercise 40 The Oral Cavity Proper The Sublingual Fold Class Exercise 41 The Floor of the Mouth The Lingual Frenum Class Exercise 42 The Floor of the Mouth The Sublingual Caruncle Class Exercise 43 Class Exercise The Oral Cavity Summary Functions o o o o Analysis Mechanical processing Lubrication limited digestion Areas o o o Mucosa Vestibule The Oral cavity proper Important landmarks o o o o o Mucogingival Junction Alveolar Mucosa Gingiva Attached & Free Gingiva Max& Man Labial Frenum o o o o o o o o o o o o o o Hard & Soft Palate Incisive Papilla Palatine Raphe Palatine Rugae Fovea Palatinae Tuberosity Hamular Notch Retromolar Pad Uvula Alveolar Process (max & man) Floor of the Mouth Sublingual Fold Lingual Frenum Sublingual Caruncle 44 Mucogingival Junction Alveolar Mucosa Maxillary Labial Frenum Free Gingiva Maxillary Vestibule Attached Gingival Mandibular Buccal Frenum Mandibular Labial Frenum Mandibular Vestibule 45
