The gingivae, commonly referred to as the gums, consists what kind of mucosa
masticatory mucosae that cover the alveolar processes of the jaws and surround the necks of the teeth
Characteristics of Normal Gingiva
Normal gingivae surround the tooth like a collar and are self-cleansing
They are firm, resistant, and can be tightly adapted to the tooth and bone
How do the surfaces of the attached gingivae and interdental papillae look like
stippled and similar in appearance to the rind of an orange
Surface color varies according to the individual’s pigmentation
Sometimes the gingivae do not completely cover the roots of the teeth and the roots become exposed. This condition, called
gingival recession [rɪˈseʃn], can lead to sensitivity and root cavities (caries).
Extension of the free gingiva that fills the interproximal embrasure between two adjacent teeth
Interdental gingiva (also called interdental papilla)

The palatal rugae
[roo·gay]

The palatine raphe
The soft palate ends posteriorly as a free edge with a hanging projection called
the uvula
The soft palate is supported posteriorly by two arches, the fauces
The anterior arch (palatoglossal arch)
and the posterior arch (palatopharyngeal arch). These are the landmarks of the soft palate.
runs from the soft palate down to the lateral aspects of the tongue
The anterior arch (palatoglossal arch)

The opening between the two arches is called
the isthmus of fauces and contains the palatine tonsil
The tongue is an important organ, responsible for several functions:
Speech
Manipulation and positioning of food
Sense of taste
Swallowing
Cleansing of the oral cavity
Tongue. The taste buds are located on
fungiform papillae (bright, red, globular) and in the trough of the large vallate papillae, which form a V on the posterior portion of the tongue
Tongue. The sense of touch is provided by
numerous filiform papillae (gray, thread-like) that cover the entire surface of the tongue.
located at either side of the lingual frenulum.
The submandibular ducts. This is one of the places where saliva enters the mouth.
Tongue’s parts and surfaces
Body: Anterior two thirds of the tongue
Root: Posterior portion that turns downward toward the pharynx
Dorsum: Upper and posterior roughened surface
Sublingual surface: Covered with smooth, transparent mucosa
Lingual frenulum: Thin fold of mucous membrane that extends from the floor of the mouth to the underside of the tongue
What is another term for unattached gingiva?
marginal gingiva or free gingiva
What is another term for interdental gingiva?
interdental papilla (plural, papillae)
What is the pear-shaped pad of tissue behind the maxillary incisors?
incisive papilla
What is the hanging projection of tissue at the border of the soft palate?
uvula [ˈjuːvjʊlə]
What is the term for upper surface of the tongue?
dorsum
What is the thin fold of mucous membrane that extends from the floor of the mouth to the underside of the tongue?
the lingual frenum
Where are lip ointments such as lip liner applied?
Lip ointments like lip liner are applied around the edges of the lips to define their shape. So, it’s referred to as the vermilion border.
What does buccal mean?
Buccal means pertaining to the cheek
Fordyce’s spots in the oral cavity. What do these spots consist of?
Fordyce’s spots (or granules) are normal small, yellowish elevations that may appear on the buccal mucosa. They consist of ectopic sebaceous glands, which are oil-producing glands that are not associated with hair follicles in these locations.
What product does the parotid produce in the oral cavity
The parotid glands produce a type of saliva that is thin and watery.
Where in the mouth are parotid papillae located
A small elevation of the tissue called the parotid papilla is located on the inner surface of the check on the buccal mucosa, just opposite the opening the second maxillary molar. The parotid papilla protects the opening of the parotid duct (Stensen’s duct) of the parotid salivary gland.
What role do the gums play in oral health?
This tissue forms a tight seal around the teeth to keep them in place and provide a barrier against bacteria. The gums supply nutrients and oxygen to the teeth through blood vessels.
Why does the color of gingivae vary?
the color of the gingiva varies depending on the degree of melanin pigmentation.
What are the landmarks of the hard palate?
Incisive papilla, palatal rugae, lingual (palatal) gingiva, median palatine raphe, ducts for palatal glands
What is another name for the underside of the tongue?
sublingual surface
What is another term used to refer to the hard palate?
roof of mouth
The Oral Cavity Proper includes
roof of mouth and floor of mouth
Which kind of papillae do not contain taste receptors?
Filiform papillae
Which teeth are usually multirooted?
Molar and premolar
Which teeth are usually single-rooted?
canine and incisor
