Accepted Answer

A variation that can be noted on the buccal mucosa is the linea alba.This is a white ridge of hyperkeratinization that extends horizontally at the level where the maxillary and mandibular teeth come together and occlude; similar ridges of white tissue can sometimes be present on the tongue perimeter.

Accepted Answer

A midline muscular structure,the uvula of the palate,hangs down from the posterior margin of the soft palate.The incisive papilla is a small bulge of tissue at the most anterior part of the hard palate.The median palatine raphe is a midline ridge of tissue on the hard palate.The palatine rugae are firm,irregular ridges of tissue on the hard palate.

Question 3

Just distal to the last tooth of the maxillary arch is a tissue-covered elevation of the bone called the:&#10;A) maxillary arch.&#10;B) maxillary tuberosity.&#10;C) canine eminence.&#10;D) retromolar pad.

Accepted Answer

Just distal to the last tooth of the maxillary arch is a tissue-covered elevation of the bone,the maxillary tuberosity.Similarly,on the lower jaw is a dense pad of tissue located just distal to the last tooth of the mandibular arch,the retromolar pad.The alveolar processes with the teeth in the alveoli are also called dental arches,the maxillary arch and mandibular arch.The facial part of the alveolus of each canine,the vertically placed canine eminence,is especially prominent on each side of the maxilla.

Question 4

Accepted Answer

A ridge of tissue on each side of the floor of the mouth,the sublingual fold,joins in a V-shaped configuration extending from the lingual frenum to the base of the tongue.The sublingual folds contain openings of the sublingual duct from the sublingual salivary gland.The labiomental groove is the natural indentation in the chin,just inferior to the lips,that takes its form from the muscles and bones lying beneath the skin.The upper and lower lips meet at each corner of the mouth at the labial commissure.

Question 5

The pink labial mucosa or buccal mucosa meets the redder _____ at the mucobuccal fold.&#10;A) marginal gingiva&#10;B) attached gingiva&#10;C) alveolar mucosa&#10;D) interdental papilla

Accepted Answer

Deep within each vestibule is the vestibular fornix,where the pink labial mucosa or buccal mucosa meets the redder alveolar mucosa at the mucobuccal fold.The gingival tissue that tightly adheres to the alveolar process surrounding the roots of the teeth is the attached gingiva.At the gingival margin of each tooth is the marginal gingiva,which forms a cuff above the neck of the tooth.The interdental gingiva is the gingival tissue between adjacent teeth adjoining attached gingiva,with each individual extension being an interdental papilla.

Question 6

The facial part of the alveolus of the ____,the vertically placed eminence,is especially prominent on the maxilla.&#10;A) premolar&#10;B) canine&#10;C) molar&#10;D) incisor

The facial part of the alveolus of each canine,the vertically placed canine eminence,is especially prominent on each side of the maxilla.The alveolar process,or alveolar bone,is the bony extension for both the maxilla and mandible that contains each tooth socket of the teeth or alveolus (plural,alveoli).

Question 7

Accepted Answer

The alveolar process,or alveolar bone,is the bony extension for both the maxilla and mandible that contains each tooth socket of the teeth or alveolus (plural,alveoli).The alveolar process,or alveolar bone,is the bony extension for both the maxilla and mandible that contains each tooth socket of the teeth or alveolus (plural,alveoli).Farther laterally is the zygomatic region,which overlies the bony support for the cheek,the zygomatic arch.On the lower jaw is a dense pad of tissue located just distal to the last tooth of the mandibular arch,the retromolar pad.

Question 8

A midline depression on the dorsal surface of the tongue is called the:&#10;A) median palatine raphe.&#10;B) sulcus terminalis.&#10;C) labiomental groove.&#10;D) median lingual sulcus.

Accepted Answer

The top,or dorsal surface of the tongue,has a midline depression,the median lingual sulcus,corresponding to the position of a midline fibrous structure deeper in the tongue and fusion tissue area.A midline ridge of tissue on the hard palate is the median palatine raphe,which overlies the bony fusion of the palate.The labiomental groove is the natural indentation in the chin,just inferior to the lips.Posteriorly on the dorsal surface of the tongue,and more difficult to see clinically,is an inverted V-shaped groove,the sulcus terminalis.

Question 9

The _____ is a white ridge of raised callused tissue that extends horizontally at the level where the maxillary and mandibular teeth come together and occlude.&#10;A) linea alba&#10;B) buccal fat pad&#10;C) parotid papilla&#10;D) labial frenum

Accepted Answer

The linea alba is a white ridge of hyperkeratinization that extends horizontally at the level where the maxillary and mandibular teeth come together and occlude; similar ridges of white tissue can sometimes be present on the tongue perimeter.The buccal mucosa covers a dense pad of underlying fat tissue at the posterior part of each vestibule,the buccal fat pad.On the inner part of the buccal mucosa,just opposite the maxillary second molar,is a small elevation of tissue is the parotid papilla.The labial frenum (plural,frena) is a fold of tissue located at the midline between the labial mucosa and the alveolar mucosa on the upper and lower dental arches.

Question 10

Which of the following oral landmarks separates the base from the body of the tongue?&#10;A) Sublingual fold&#10;B) Lingual tonsil&#10;C) Plica fimbriatae&#10;D) Sulcus terminalis

Accepted Answer

Posteriorly on the dorsal surface of the tongue is an inverted V-shaped groove,the sulcus terminalis; it separates the base from the body of the tongue,demarcating a line of fusion of tissue during the tongue's development.A ridge of tissue on each side of the floor of the mouth,the sublingual fold,joins in a V-shaped configuration extending from the lingual frenum to the base of the tongue; it contains openings of the sublingual duct from the sublingual salivary gland.Even farther posteriorly on the dorsal surface of the base of the tongue is an irregular mass of tissue,the lingual tonsil.Lateral to each deep lingual vein on the ventral surface of the tongue is the plica fimbriata (plural,plicae fimbriatae) with fringelike projections.
