Chapter 02: Oral Cavity and Pharynx(detailed and latest to score the best grade)(GRADED A+)

1. Which of the following oral landmarks may be noted on the soft palate? a. Incisive papilla b. Palatine rugae c. Median palatine raphe d. Uvula ANS: D 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. REF: Chapter 2, Palate, Page 15 2. Which of the following oral landmarks separates the base from the body of the tongue? a. Sublingual fold b. Lingual tonsil c. Plica fimbriatae d. Sulcus terminalis ANS: D 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. REF: Chapter 2, Tongue, Page 15 3. Which of the following statements concerning Fordyce spots is correct? a. Composed of salivary gland tissue b. Located on the attached gingiva c. Composed of sebum from sebaceous tissue d.
