Regions of the Head

Frontal, parietal, occipital, temporal, auricular, orbital, nasal, infraorbital, zygomatic, buccal, oral, and mental.

Vermilion Border or Zone

Darker appearance than surrounding skin

Mucocutaneous Junction

Lips are outlined from surrounding skin by a transition zone.


Superior to midline of upper lip, extending downward from nasal septum, is a vertical groove.

Tubercle of the Upper Lip

Inferior to philtrum, midline of the upper lip terminates in a thicker area.

Labial Commissure

Upper and lower lips meet at each corner of the mouth.

Nasolabial Sulcus

Groove running upward between each labial commissure and each ala of the nose.

Labiomental Groove

Lower lip extends horizontally. Separates the lower lip from the chin in the mental region.

Labial Mucosa

Lining of inner part of lips that are pink and thick.

Buccal Mucosa

Continuous with labial mucosa, but lines inner cheek and are pink and thick.

Parotid Papilla

Inner part of buccal mucosa, just opposite maxiallary second molar. It is a small elevation of tissue that protects the duct opening from the parotid salivary gland.

Maxillary/ Mandibular Vestibules

Upper and lower horseshoe shaped spaces in oral cavity between lips and cheeks anteriorly and laterally and the teeth and their soft tissue medially and posteriorly.

Labial Frenum

Fold(s) of tissue located at midline between labial mucosa and alveolar mucosa on both maxilla and mandible.

Attached Gingiva

Gingiva that tightly adheres to the bone around to the bone around the roots of the teeth.

Mucogingival Junction

Line of demarcation between firmer and pinker attached gingiva and the movable and redder alveolar mucosa.

Marginal Gingiva/Free Gingiva

Nonattached at the gingival margin of each tooth.

Gingival Sulcus

Inner surface of marginal ginvia.

Interdental Gingiva/ Interdental Papilla

Extension of attached gingiva between the teeth.

Pterygomandibular Fold

Fold of tissue that extends from the junction of the hard and soft palates on each side down to the mandible, just posterior to the most distal mandibular molar and stretches when the patient opens the mouth wider.

Foliate Lingual Papillae

Noted on the side of the lateral surface of the tongue for its vertical ridges.

Filiform Lingual Papillae

Give dorsal surface its velverty texture

Fungiform Lingual Papille

Red mushroom shaped dots. More numerous on the apex and contain taste buds.

Sulcus Terminalis

V-shaped groove, that separates base from the body of the tongue.

Circumvallate Lingual Papillae

10-14 in umber, line up along anterior side of sulcus terminalis on the body. Large mushroom shaped lingual papillae have taste buds.

Sublingual Fold/Plica sublingualis

Ridge of tissue on each side of the floor of the mouth. THese folds are arranged in a V-shaped configuration from lingual frenum to base of tongue. They contain duct openings from sublingual salivary gland.

Sublingual Caruncle

Small papilla at the anterior end of each sublingual fold containing openings from both submandibular and sublingual salivary glands.

Fauces/Faucial isthmus

Opening from oral region into oropharynx.

Anterior Faucial Pillar/ Posterior Faucial Pillar

Fauces formed laterally on each side.

Superior boundary of mouth

Hard and soft palates

Inferior boundary of mouth

Tongue and floor of mouth

Anterolateral boundary of mouth

Upper and lower teeth

Posterior boundary of the mouth

Palatoglossal fold

Another name for palatoglossal arch

Anterior faucal pillar

Another name for palatopharyngeal arch

Posterior faucal pillar

Largest Duct

Sublingual Duct

Duct of Bartholin

Submandibular Duct

Wharton's Duct

Parotid Papilla Duct

Opening of Stenson's Duct

Sublingual Caruncle

Site on either side of the lingual frenum. There it denotes the site at which the submandibular gland and the sublingual gland empty into the oral cavity.

Sulcus Terminalis

Divides base and body of tongue

Sublingual salivary glands lie

anterior to submandibular gland under the tongue.

Forms the sublingual fold and send multiple small ducts into the mouth along the fold.

Sublingual Gland
