LINEA ALBA

“Linea” means __; “alba” means ___.

line, white

normal malignancy

linea alba leukoplakia

-spots are small, yellowish irregular areas and may be conspicuous in some persons.

FORDYCE’S GRANULES

-They are most commonly located on the buccal mucosa inside the cheeks posterior to the corner of the mouth

FORDYCE’S GRANULES

is the firm anterior part of the roof of the mouth with mucosa over the underlying bone

HARD PALATE

is the posterior movable part of the roof of the mouth without underlying bony support.

SOFT PALATE

ROOF OF THE MOUTH

PALATE

the small rounded elevation of tissue on the midline of the palate just lingual to the central incisors.

Incisive Papilla

are a series of palatal tissue elevations, or wrinkles, located on the palate just posterior the maxillary anterior teeth

Palatal Rugae

tactilely sensing objects or food position and in aiding the tongue proper placement for the production of certain speech sounds.

Palatal Rugae

it separates the mouth from the nasal passage. It is sometimes redder than the hard palate because of its slightly increased vascularity.

Vibrating Line

are a pair of pits in the soft palate located on either side of the midline, near but just posterior to the vibrating line.

Fovea Palatini

They are openings of ducts of minor palatine mucous glands

Fovea Palatini

Fovea means Palatini means

small hollow Palate

is a small fleshy structure hanging from the center of the posterior border of the soft palate

Uvula

Uvula means

Uva (grapes)

rests in the floor of the mouth within the curved body of the mandible.

Tongue

changes its shape with each functional movement.

Tongue

is the principal organ of taste and is invaluable during speech, mastication, and deglutition.

Dorsum of the Tongue

lateral surfaces of the tongue seen when a person sticks out the tongue.

foliate papillae

large, red, leaf-like projections.

foliate papillae

sparse, scattered, and shorter. mushroom-like.

fungiform papillae

identify because of their larger round shape and deep red color.

fungiform papillae

concentrated near the tip of the tongue

fungiform papillae

forming a V-shaped row on the dorsum near the posterior third of the tongue.

circumvallate papillae

Fine hair-like which are quite numerous, cover the anterior two thirds of the dorsal surface of the tongue.

filiform papillae

undersurface of the tongue is shiny, and blood vessels are visible.

Ventral of the Tongue

is a thin sheet of tissue at the midline that attaches the undersurface of the tongue to the floor of the mouth.

Lingual frenum

are delicate fringes of mucous membrane on each side of the frenum on the ventral surface of the tongue.

Plica fimbriata

Plica means fibriata means

folds fringe

are shiny, and some large blood vessels may be seen near the surface

Floor of the mouth

is the broad, valley-shaped space between the mandibular alveolar bone and the tongue.

Alveololingual sulcus

to examine (a part of the body) by touch, especially for medical purposes

Palpation

Palpation of the cheeks (or lips) for lumps or bumps can be accomplished by pressing with the thumb on one side against the forefinger on the other side

Bidigital Palpation

using the opposing fingers of two hands) in order to feel for lumps or bumps (like a salivary duct blockage) within the floor of the mouth.
