Which of the following facial features is located laterally to each naris? ANS: B The nares are separated by the midline nasal septum. The nares are also bounded laterally by winglike cartilaginous structures, each ala (plural, alae) of the nose. In the orbital region of the face, the eyeball and all its supporting structures are contained in the orbit of the skull, the bony eye socket. On the midline of the upper lip extending downward from the nasal septum is a vertical groove, the philtrum. REF: Chapter 1, Nasal Region, Page 2 2. The lips are outlined from the surrounding skin by a transition area called the: ANS: C The vermilion zone of each lip has a darker appearance than the surrounding skin, with the lips outlined from the surrounding skin by a transition zone, the mucocutaneous junction. On the midline of the upper lip extending downward from the nasal septum is a vertical groove, the philtrum. The line of demarcation between the firmer and pinker attached gingiva and the movable and redder alveolar mucosa is the scallop-shaped mucogingival junction. The midline of the mandible is marked by the mandibular symphysis. REF: Chapter 1, Oral Region, Page 2 3. Which of the following structures can be palpated in the anterior midline of the neck? a.

Philtrum a. philtrum. b. mucogingival junction. c. mucocutaneous junction. d. mandibular symphysis. glands are located close to or within the posterior aspect of the thyroid gland but cannot be palpated in a patient; the thyroid gland can be palpated on a patient within the midline cervical area. The large strap muscle, the sternocleidomastoid muscle, is easily palpated on each side of the neck. The submandibular salivary gland is in the neck region but not in the midline. REF: Chapter 1, Neck Regions, Page 8 4. One of the muscles forming the cheek is the strong _____ muscle, which is felt when a patient clenches the teeth together. ANS: B The buccal region of the face is composed of the soft tissue of the cheek. The cheek forms the side of the face and is a broad area of the face between the nose, mouth, and ear. Most of the upper cheek is fleshy, mainly formed by a mass of fat and muscles. One of the muscles forming the cheek is the strong masseter muscle, which is palpated when a patient clenches the teeth together. The pterygoid muscles are also located on each side of the face near the mouth, and the temporalis is located in the temporal region. REF: Chapter 1, Buccal Region, Page 2 5. Just inferior to the zygomatic arch and just anterior to the external ear is the: ANS: A Inferior to the zygomatic arch and just anterior to the external ear is the temporomandibular joint. The infraorbital region of the face is located inferior to the orbital region and lateral to the nasal region. Farther laterally is the zygomatic region, which overlies the bony support for the cheek, the zygomatic arch. The zygomatic arch extends from just below the lateral margin of the eye toward the middle part of the external ear. The chin is the major feature of the mental region of the face; the bone underlying the mental region is the mandible, or lower jaw. The parotid is located irregularly from the zygomatic arch down to the posterior border of the lower jaw. REF: Chapter 1, Zygomatic Region, Page 2 6. The _____ salivary gland is located irregularly from the zygomatic arch down to the posterior border of the lower jaw. a. lateral pterygoid b. masseter c. medial pterygoid d. temporalis a. temporomandibular joint. b. infraorbital region. c. mental region. d. parotid gland. ANS: A The parotid is located irregularly from the zygomatic arch down to the posterior border of the lower jaw. Both the submandibular salivary and sublingual are in the neck region. The von Ebner refers to minor glands located deep to the circumvallate lingual papillae on the dorsal surface of the tongue. REF: Chapter 1, Buccal Region, Page 2 7. The _____ extends from just below the lateral margin of the eye toward the middle part of the external ear. ANS: B The zygomatic arch extends from just below the lateral margin of the eye toward the middle part of the external ear. Inferior to the zygomatic arch and just anterior to the external ear is the temporomandibular joint. The upper and lower lips meet at each corner of the mouth at the labial commissure. The infraorbital region of the face is located inferior to the orbital region and lateral to the nasal region. REF: Chapter 1, Zygomatic Region, Page 2 8. The main feature of the _____ region of the face is the external nose. ANS: C The main feature of the nasal region of the face is the external nose. The infraorbital region of the face is located inferior to the orbital region and lateral to the nasal region. Farther laterally is the zygomatic region, which overlies the bony support for the cheek, the zygomatic arch. The temporal region is on the lateral side of the head at the temple. REF: Chapter 1, Nasal Region, Page 1 9. Which of the following orofacial structures is located in the midline of the face or neck? a. parotid b. submandibular c. von Ebner d. sublingual a. temporomandibular joint b. zygomatic arch c. labial commissure d. infraorbital region a. infraorbital b. zygomatic c. nasal d. temporal ANS: A On the midline of the upper lip extending downward from the nasal septum is a vertical groove, the philtrum. The submandibular can also be palpated in a patient in the neck region but not in the midline. Inferior to the apex on each side of the nose is a nostril, or naris (plural, nares). The nares are also bounded laterally by winglike cartilaginous structures, each ala (plural, alae) of the nose. The parotid is located irregularly from the zygomatic arch down to the posterior border of the lower jaw and not in the midline. REF: Chapter 1, Oral Region, Page 2 10. The _____ region includes the forehead and area above the eyes. ANS: D The frontal region of the face includes the forehead and the area above the eyes. The infraorbital region of the face is located inferior to the orbital region and lateral to the nasal region. In the orbital region of the face, the eyeball and all its supporting structures fare contained in the orbit of the skull, the bony eye socket. The temporal region is on the lateral side of the head at the temple. REF: Chapter 1, Frontal Region, Page 1 11. Which of the following statements concerning the zygomatic arch is correct? a. The temporomandibular joint is superior. b. The infraorbital region is inferior. c. It overlies the mandible. d. The external ear is posterior. ANS: D Farther laterally to the infraorbital region is the zygomatic region, which overlies the bony support for the cheek, the zygomatic arch. The zygomatic arch extends from just below the lateral margin of the eye toward the middle part of the external ear, which is located posteriorly. Inferior to the zygomatic arch and just anterior to the external ear is the temporomandibular joint. a. Philtrum b. Submandibular salivary gland c. Naris and ala d. Parotid salivary gland a. infraorbital b. orbital c. temporal d. frontal REF: Chapter 1, Zygomatic Region, Page 2 12. Which of the following may be involved in the disruption of the vermilion zone and may make it hard to determine the exact location of its mucocutaneous junction between the lips and the surrounding skin? ANS: A Disruption of the vermilion zone may make it hard to determine the exact location of its mucocutaneous junction between the lips and the surrounding skin. These changes may be due to scar tissue from past traumatic incidents, developmental disturbances, or cellular changes in the tissue such as occur with solar damage. These changes may also represent a more serious condition such as cancer; however, this can be verified only with tissue biopsy and microscopic examination. If this change is part of a past history of a cleft lip, this also needs to be noted in the patient record because of its impact on dental care. REF: Chapter 1, Clinical Considerations with Lips, Page 2 13. The _____ region of the face is composed of the soft tissue of the cheek. ANS: D The buccal region of the face is composed of the soft tissue of the cheek. The infraorbital region of the face is located inferior to the orbital region and lateral to the nasal region. In the orbital region of the face, the eyeball and all its supporting structures are contained in the orbit of the skull, the bony eye socket.
