10. Each of the following has a role in trapping contaminants that enter the nasal cavity EXCEPT one. Which one is the EXCEPTION? a. Cilia b. Mucous c. Goblet cells d. Olfactory epithelium e. All of the above help to trap contaminants. ANSWER : D The respiratory epithelium has cilia, mucous, and goblet cells that remove contaminants from the nasal cavity. The conchae also are helpful. The olfactory epithelium, a modification of the respiratory epithelium, does not perform these functions. RE: p. 313 OBJ: To describe the function of the nasal cavity, nasal epithelium, and paranasal sinuses NAT: CDA: GC I.A. Identify basic oral and dental anatomy, physiology and development. UPPER: BLOOM: Remembering 11. Under normal circumstances, sinuses are filled with a. fluid b. blood c. air d. bones of the cranium ANSWER : C The sinuses are hollow cavitiNes tRhat IfuncGtionBt.o ClighMten the overall bone weight. When they become irritated or infected they fill with inflammatory fluid as a result of mucous edema. RE: p. 317 OBJ: To understand the anatomy of the nose, nasal cavity, and paranasal sinuses NAT: CDA: GC I.A. Identify basic oral and dental anatomy, physiology and development. UPPER: BLOOM: Remembering 12. The deeper sinuses, particularly the ethmoid, are most commonly involved in sinus infections that are difficult to localize. A new opening can be surgically created to assist with proper drainage. Note that the maxillary sinuses, while not as deep, commonly become infected. a. Both statements are correct . b. The first statement is correct ; the second statement is false. c. The first statement is false; the second statement is correct . d. Both statements are false. ANSWER : C Infections of the paired sphenoid sinuses cause pressure and congestion that are difficult to localize. These sinuses are located in the middle of the cranial fossa and the pressure associated with infections is deep in the middle of the head. RE: p. 315 OBJ: To describe the relationship of maxillary teeth to the maxillary sinus in infections of either one NAT: CDA: GC I.A. Identify basic oral and dental anatomy, physiology and development. UPPER: BLOOM: Understanding 13. The crescent-shaped groove within the middle nasal concha is the a. sphenoethmoid recess b. hiatus semilunaris c. ethmoid bulla d. nasal aperture ANSWER : B The hiatus semilunaris, which me Answer half-moon shaped opening, lies within the middle nasal concha just above the middle meatus. The sphenoethmoid recess is the highest and most posterior part of the nasal cavity. The ethmoid bulla is an elevation within the ethmoid sinuses. The nasal aperture is the opening to the nose. RE: pp. 315-316 OBJ: To understand the anatomy of the nose, nasal cavity, and paranasal sinuses NAT: CDA: GC I.A. Identify basic oral and dental anatomy, physiology and development. UPPER: BLOOM: Remembering 14. The cilia have hairlike projections that perceive odors because they are located within the olfactory epithelium. a. Both the statement and the reason are right and related. b. Both the statement and the reason are right but are NOT related. c. The statement is right , but the reason is NOT right . d. The statement is NOT right , but the reason is right . e. NEITHER the statement NOR the reason is right . ANSWER : E The cilia have hairlike projecNtionRs thIat mGoveBc.oCntamMinants toward the front of the nasal passages. They are located within the respiratory epithelium. The olfactory epithelium, a modification of respiratory epithelium, has nerve endings that perceive odors. RE: p. 313 OBJ: To describe the function of the nasal cavity, nasal epithelium, and paranasal sinuses NAT: CDA: GC I.A. Identify basic oral and dental anatomy, physiology and development. UPPER: BLOOM: Understanding 15. Infections of the frontal sinuses can cause pressure and pain just above the eye because these sinuses are located just above the orbital cavity. a. Both the statement and the reason are right and related. b. Both the statement and the reason are right but are NOT related. c. The statement is right , but the reason is NOT right . d. The statement is NOT right , but the reason is right . e. NEITHER the statement NOR the reason is right . ANSWER : A The paired frontal sinuses are located in the frontal bone just above the orbital cavity. Infections of the frontal sinuses cause pain and pressure just above the eye. These sinuses vary in size from person to person and frequently cross the midline. RE: p. 315 OBJ: To describe the relationship of maxillary teeth to the maxillary sinus in infections of either one NAT: CDA: GC I.A. Identify basic oral and dental anatomy, physiology and development. UPPER: BLOOM: Understanding
