Chapter 01: Face and Neck Regions
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 philtrum.
REF: Chapter 1, Nasal Region, Page 2
2. The lips are outlined from the surrounding skin by a transition area called
the:
a. philtrum.
b. mucogingival junction.
c. mucocutaneous junction.
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
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.

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

, Illustrated Dental Embryology, Histology, and Anatomy
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?
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.
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.
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.
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
6. Just inferior to the zygomatic arch and just anterior to the external ear is the:
a. temporomandibular joint.
b. infraorbital region.
c. mental region.
d. parotid gland.
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
7. The salivary gland is located irregularly from the zygomatic arch down
to the posterior border of the lower jaw.
a. parotid
b. submandibular
c. von Ebner
d. sublingual
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.

8. The extends from just below the lateral margin of the eye toward the
middle part of the external ear.
a. temporomandibular joint
b. zygomatic arch
c. labial commissure
d. infraorbital region
