MULTIPLE CHOICE
1. Which of the following facial features is located laterally to each naris?
a. Orbit
b. Nasal ala
c. Nasal septum
d. Philtrum
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
PR
philtrum.
REF: Chapter 1, Nasal Region, Page 2
2. The lips are outlined from the surrounding skin by a transition area called
the:
O
a. philtrum.
b. mucogingival junction.
c. mucocutaneous junction.
FD
d. mandibular symphysis.
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
O
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
C
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. Thyroid cartilage
b. Parathyroid glands
c. Sternocleidomastoid muscle
d. Submandibular salivary gland
, ANS: A
Found in the anterior midline and inferior to the hyoid bone is the thyroid
cartilage, which is the prominence of the “voice box,” or larynx. The vocal cords,
or ligaments of the larynx, are attached to the posterior surface of the thyroid
cartilage. The parathyroid 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. Which of the following statements concerning the zygomatic arch
is correct?
PR
a. The temporomandibular joint is
superior.
b. The infraorbital region is inferior.
c. It overlies the mandible.
d. The external ear is posterior.
O
ANS: D
Farther laterally to the infraorbital region is the zygomatic region, which
FD
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.
REF: Chapter 1, Zygomatic Region, Page 2

5. One of the muscles forming the cheek is the strong muscle, which
is felt when a patient clenches the teeth together.
C
a. lateral pterygoid
b. masseter
c. medial pterygoid
d. temporalis
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.
