Study Notes
Oral Cavity Structures
- The gingiva is the tissue that surrounds the cervical part of teeth.
- The lingual frenulum is the structure in the oral cavity where the tongue meets the floor of the mouth.
Salivary Glands
- The floor of the mouth contains two bilateral bulges caused by the presence of large salivary glands.
Roof of the Mouth
- The roof of the mouth is divided into the hard palate and the soft palate.
- The anterior part of the roof of the mouth is called the hard palate.
- The posterior part of the roof of the mouth is called the soft palate.
Teeth
- The process of teeth moving from their location within the alveolar crypt into a functional position in the oral cavity is called tooth eruption.
- The natural physiological elimination of deciduous teeth is called shedding.
- The shedding of deciduous teeth occurs after the eruption of their permanent successors.
Tongue and Palate
- The tongue is involved in the processes of speech, mastication, and swallowing, and is the principle organ of taste.
- The uvula is the small fleshy structure at the end of the soft palate.
Lips and Mouth
- The structure in the oral cavity where the two lips meet is called the linea alba buccalis.
- The two grooves distinguished around the lips are the nasolabial groove and labiomental groove.
