- Tonsils: Immune system tissues located at the back of the throat.
- Soft palate: The muscular back part of the roof of the mouth.
- Oropharynx: The part of the throat below the soft palate.
- Palatoglossal arch: Ridges of tissue connecting the soft palate to the tongue.
TEMA 3: Dental Instruments and Procedures
