General structures of the digestive system:
- Oral Cavity
- Pharynx
- Oesophagus
- Stomach
- Small intestine
- Large Intestine
Accessory Organs
- Teeth
- Tongue
- Salivary glands
- Liver
- Pancreas
- Gall Bladder
External Structures of the Mouth:
- Upper Lip (Labium Superior)
- Lower Lip (Labium Inferior)
- Oral Angle (Labial Commissure)
- Nasolabial Sulcus (Sulcus Nasolabialis)
- Philtrum
- Mentolabial Sulcus (Sulcus Mentolabialis)
- Oral Fissure (Rima Oris)
Division of the Oral Cavity:
- Oral Vesitibule (Vestibulum Oris)
- Oral Cavity Proper (Cavitas Oris Propria)
Oral Vestibule:
- External Borders: Lips and Cheeks
- Internal Borders: Teeth and Gums
Anatomy of the Lips:
- Frenulum of the Upper Lip (Frenulum Labii Superioris)
- Frenulum of the Lower Lip (Frenulum Labii Inferioris)
- Labial Glands (Glandulae Labialis)
Anatomy of the Cheeks:
- Buccinator Muscle (musculus buccinator)
- Buccopharyngeal Fascia
- Buccal Fat Pad (Bichat's Fat Pad)
- Layers of the Skin (cutis)
- Tunica Mucosa
- Parotid Duct (Ductus Parotideus)
- Papilla of the Parotid Duct (Papillae Ductus Parotidei)
Anatomy of the Teeth:
- Crown of the tooth (Corona Dentis)
- Root of the tooth (Radix Dentis)
- Neck of the tooth (Cervix Dentis)
- Periodontium
- Gomphosis (Dentoalveolar Joint)
- Dental Pulp (Pulpa Dentis)
- Root Canal (Canalis Radicis Dentis)
- Apical Foramen (Foramen Apicis Dentis)
- Dentin (Dentinum)
- Enamel (Enamelum)
- Cement (Cementum)
- Milk Teeth (Dentes decidui) 20 teeth, begins at 6th moth of life and ends at 24th month of life
- Replacement of milk teeth at age of 6-12 years
- Permanent Teeth (Dentes Permanentes) 32 teeth
- Wisdom teeth (dentes serotinus) appears at the age of 17-24 years
Tooth Arrangement:
PS! European way of arrangement
- First we divide the teeth into 4 equal quadrants
- First 2 teeth are called Incisor Teeth (Dentes Invisivi)
- Next teeth are Canine Teeth (Dentes Canini)
- Premolar Teeth (Dentes Premolares)
- Molar Teeth (Dentes Molares)
- 8*4=32 means we have 32 premanent teeth
- Milk Teeth have two incisor teeth, one canine tooth and two molar teeth
Anatomy of the Gums (Gingiva):
- Alveolar Mucus Membrane (Covers at the level of root of the tooth. Contains a lot of submucosal Connective tissue)
- Gum Proper (attached to the periosteum)
- Gingival Papillae (papillae gingivales)
- Gingival Margin (margo gingivalis)
- Gingival Sulcus (sulcus gingivalis)
