Anatomy- Upper Digestive System
| Term | Answer |
|---|---|
| GI Tract Layers | four layers of tissues from out to in: serosa, muscularis, submucosa, and mucosa |
| Upper Digestive Tract | Tongue, pharynx, esophagus, stomach |
| Parts of the Mouth | lips, cheeks, hard/soft palate, tongue, tonsil, uvula, epiglottis, pharynx, salivary glands, teeth |
| Hard Palate | four bones: two maxillae and two palatines |
| Soft Palate | between the mouth and nasopharynx, a muscle arranged in the shape of an arch. |
| Fauces | opening in the arch leads from the mouth into the oropharynx |
| Uvula | Suspended from the midpoint of the posterior bor-der of the arch is a small cone-shaped process, |
| Parotid (salivary) Glands | penetrate the buccinator muscle on each side and open into the mouth, produce a watery (or serous) type of saliva containing enzymes but not mucus |
| Submandibular (salivary) Glands | located just below the mandibular angle, contain both serous (enzyme) and mucus-producing elements |
| Sublingual (salivary) Glands | smallest, in front of the submandibular glands, under the mucous membrane covering the floor of the mouth, 8-20 ducts, produce only a mucous type of saliva |
| Tooth from Top to Bottom | Cusp, Crown, Neck, Root |
| Tooth from Out to In | Enamel (covers exposed), Cementum (covers root), Dentin (hard CT), Pulp (soft CT) |
| Pharynx | swallowing/Deglutition, pushes food to esophagus in terminal portion |
| Esophagus | collapsible, muscular, mucosa-lined tube from pharynx to stomach |
| Stomach | esophagus-gastrointestinal opening, cardia, lesser (upper) and greater (lower) curvature, fundus (top), body, pylorus (bottom), pyloric sphincter, duodenal bulb, duodenum |
| Stomach from Out to In | Serosa, longitudinal muscle, circular muscle, oblique muscle, submucosa, mucosa, rugae (ridges in) |
