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.

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.

ANS: A

, TESTBANKSELLER.COM
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.

4. Which of the following statements concerning the zygomatic arch is correct?
a. Temporomandibular joint is superior.
b. Infraorbital region is inferior.
c. It overlies mandible.
d. 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.

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.

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.

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
