Study Notes
Oral Region
- The oral cavity is the space between the upper and lower dental arches
- It has boundaries: teeth and dental arches, posterior: communicates with the oropharynx, roof: hard and soft palate
- It's fully occupied by the tongue when the mouth is closed
Swallowing
- Swallowing happens in two stages: oropharyngeal and esophageal
- The oropharyngeal stage starts when food is pressed against the tongue, at the roof of the mouth, and backwards towards the pharynx
Oral Vestibule
- Communicates with the exterior through the oral fissure
- Space between teeth and gingiva, and lips and cheeks
- Its size is controlled by perioral muscles (orbicularis oris, buccinator, risorius, depressors and elevators of the lips)
Gingivae
- Composed of fibrous tissue covered with mucous membrane
- Gingiva propria is firmly attached to the alveolar processes of the maxilla and mandible
- It covers the roots of the teeth and is normally pink, stippled, and keratinizing
- Different gingivae types include maxillary, buccal, and lingual
Teeth
- Deciduous (primary) teeth erupt between 6-10 months and are shed between 6-7 years
- Permanent teeth erupt between 6-7 to 13-25 years
- Children have 20 deciduous teeth, supplied by superior labial branches of the infraorbital nerves and maxillary branches of the trigeminal nerves
- 32 permanent teeth
Lips, Cheeks, and Gingivae
- Lips are mobile folds of musculo-fibrous tissue surrounding the mouth
Tongue
- The tongue has a body, apex (tip), and root, with sensory and motor functions controlled by multiple cranial nerves
- The tongue helps with speech, mastication (chewing), and swallowing
- Its underside (inferior surface) is covered by a thin layer of mucous membrane with no papillae
Esophagus
- Expanded part of the digestive tract between the esophagus and the small intestine
- Functions: accumulating ingested food, food blender, reservoir, and chief enzymatic digestion processes
- Major parts: cardia (receives terminal portion of the esophagus), fundus (dilated superior part), body (main portion between fundus and pyloric antrum), pyloric part (funnel-shaped region leading to the duodenum)
Stomach
- Expanded part of the digestive tract, acting as a food reservoir, blender, and site for enzymatic digestion.
- Has four parts: cardia (receives esophagus), fundus (superior portion), body (middle part), pyloric part (funnel-shaped distal region)
- Two curvatures: lesser curvature (shorter) at the right border and greater curvature (longer) at the left border.
Salivary Glands
- Submandibular gland
- Sublingual gland
- Parotid gland
Diseases of the Oral Cavity
- Cleft lip/palate
- Cyanosis (bluish discoloration) of the lips
Neurovasculature of the Esophagus
- Arterial supply to the cervical esophagus comes from inferior thyroid artery
- Arterial supply to the thoracic part of the esophagus comes from the branches of the thoracic aorta (including bronchial arteries) and esophageal arteries
- Arterial supply to the abdominal esophagus comes from the ascending branches of the left phrenic arteries and left gastric arteries
Lymphatic Drainage of the Stomach
- Lymph nodes draining from the stomach usually follow the arterial supply, including nodes at the lesser and greater curvatures, and suprapyloric nodes
- Lymphatic vessels accompany arterial tributaries draining into the nearest lymph nodes
