vestibule

Horse-shoe shaped spaces between the lips and cheeks and the teeth

maxilla

immovable, upper jaw

Fordyce's spots

linea alba

Uvula

What is the structure labeled #3?

Sulcus terminalis

What oral landmark separates the base from the body of the tongue?

mucogingival junction

The line of demarcation between the attached gingiva and the alveolar mucosa

Sublingual folds

Fold or groove of tissue located on the floor of the mouth

median lingual sulcus

midline depression on the dorsal surface of the tongue

buccal mucosa

Location of linea alba

Exostoses

mandibular torus

enamel

hard outer layer of the crown

cementum

outermost layer of the root

dentin

moderately hard inner layer overlying the pulp

retromolar pad

dense pad of tissue located just distal to the last tooth of the mandibular arch

maxillary tuberosity

tissue-covered elevation of bone distal to the last tooth of the maxillary arch

incisive papilla

Small bulge of tissue at the most anterior part of the hard palate

palatal torus

normal variation of bony growth at the midline of the hard palate

filiform papillae

slender, threadlike, whitish papillae. Give tongue a velvety appearance.

fungiform papillae

smaller mushroom-shaped dots on the dorsal surface of tongue

circumvallate

larger mushroom-shaped papillae that line up along the sulcus terminalis

sublingual caruncle

small papilla at the anterior end of each sublingual fold that contains openings of the submandibular duct (Wharton's duct) and sublingual duct (Bartholin's duct).

plica fimbriate

fringelike projections lateral to each deep lingual vein

alveolar processes

bony extensions of the maxilla and mandible that contain each tooth socket of the teeth

dorsal

top of tongue

ventral

underside of tongue

oropharynx

part of pharynx that is between the soft palate and the opening of the larynx

mandible

lower jaw, movable

attached gingiva

gingival tissue that tightly adheres to the bone around the roots of the teeth
