Study Notes
Oral Anatomy Landmarks
- Labiomental groove is a landmark between the lower lip and chin.
- Philtrum is the vertical groove between the upper lip and nose.
- Vermilion refers to the border of the lip where it meets the skin.
- Nasolabial sulcus is the groove extending from the side of the nose to the corner of the mouth.
Hard Palate Structures
- Tori are benign bony overgrowths found on the hard palate.
- Rugae are soft tissue structures covering the median palatine suture.
- Incisive papilla is a small, raised area located at the anterior part of the hard palate.
- Raphe is a fibrous structure that runs down the center of the hard palate.
Oral Cavity Features
- Parotid papilla is located on the buccal mucosa, specifically near the second maxillary molar.
- Masticatory mucosa is present in the gingiva, providing a sturdy surface for chewing.
- Buccal frena are connective tissues attaching the lips to the gums.
Frena Types
- Buccal frena are the most numerous type of frena found in the oral cavity.
- Labial frena are attached to the upper and lower lips.
- Lingual frena connect the tongue to the floor of the mouth.
Tongue Anatomy
- Foliate papillae are located on the lateral surface of the tongue, aiding in taste sensation.
- Dorsum of the tongue is the upper surface where different papillae are found.
- The apex of the tongue is its tip, while the ventral surface is its underside.
Oral Cavity Boundaries
- The most inferior boundary of the oral cavity is the floor of the mouth.
- The oropharynx serves as the next region beyond the oral cavity, involved in swallowing.
Arch Positioning
- The palatoglossus arch is more anterior compared to palatopharyngeal and palatolarynx arches.
