Study Notes
Dental Structure
- Monophyodont: One set of teeth, e.g., platypus, toothed whale
- Diphyodont: Two sets of teeth, milk (temporary) and permanent, e.g., mammals
- Polyphodont: Teeth can be replaced many times, e.g., frog
- Isodont (Homodont): All teeth similar, e.g., toothed whale
- Heterodont: More than one type of teeth, e.g., four types in humans:
- Incisors (cutting)
- Canines (tearing)
- Premolars (grinding)
- Molars (grinding, not present in milk dentition)
- Pleurodont: Teeth fixed by sides to lateral surface of jaw ridge, e.g., reptiles
- Bunodont: Low cusps, e.g., humans
- Lophodont: Transverse ridges, e.g., elephant
- Solenodont: Crescent-shaped cusps, e.g., sheep
- Secodont: Cusps pointed, e.g., carnivores
Alimentary Canal
- Pharynx: It lies between the cal vary parts of nasal and oral cavities, connected to the eustachian tube and uvula
- Oesophagus: It communicates through the diaphragm and opens into the stomach
- Stomach: Part of the alimentary canal, located behind the diaphragm, has a cardiac part at the anterior end
